There will be two minutes added on at the end of this match.
89'
Iván Marcano gets yellow.
Frustration setting in now as Marcano goes into the book.
88'
HOW UNLUCKY! Khedira has put in such an impressive display tonight and you really couldn't say he doesn't deserve a goal for his efforts. He tirelessly chases a throughball, arriving just ahead of Casillas as he slides in to send an effort towards goal, missing the far post by mere fractions.
86'
C. Marchisio enters the game and replaces P. Dybala.
The final Juventus change of the night sees Claudio Marchisio replace Dybala.
85'
H. Herrera gets yellow.
Back the other way come Juventus on the break, and Herrera takes one for the team, sliding in to foul Pjaca and stop a break as he's issued a yellow card.
84'
It took 84 minutes, but Porto finally have their first corner of the night. Layun takes it, as the hosts pack bodies in the centre, but it's seen away smartly by Mandzukic.
82'
The tempo is slowing a great deal with Juventus content with their advantage, knocking the ball about as they look to milk the final minutes off the clock. The last thing they want now is to give Porto a glimmer of hope. They need not worry about scoring a third goal.
80'
STAT: Juventus are unbeaten against Porto (W2 D1). They beat them in the 1984 Cup Winners' Cup final (2-1), and recorded a win (3-1) and a draw (0-0) when they met in the 2001/02 Champions League first group stage.
78'
Fatigue is creeping in as well now for Porto, who are barely hanging on as Juventus control possession and poke and prod in search of a third goal. The hosts' resistance has been broken and their resolve is being tested.
Minute
Description
76'
Well you get the sense that the tie is about settled now. It could have been very different had Alex Telles not gone and got himself sent off so early on, but that's the way it works sometimes. Goals from a pair of Juventus substitutes have likely put this tie to bed.
74'
Dani Alves has scored a goal for Juventus! Assist by Alex Sandro.
TWO GOALS FROM THE SUBSTITUTES! He's hardly been on the pitch for 60 seconds, but Dani Alves gets on the end of a cross from Sandro, chests it down and just manages to tuck home a finish with Marcano late arriving!
Alex Sandro has been exceptional tonight and he deserves that assist.
73'
Dani Alves enters the game and replaces S. Lichtsteiner.
Diogo Jota enters the game and replaces Y. Brahimi.
Porto's third and final change sees Diogo Jota replace Brahimi.
Dani Alves replaces Lichtsteiner, a likey precaution with the Swiss full-back on a booking.
72'
M. Pjaca has scored a goal for Juventus!
JUVENTUS HAVE THEIR BREAKTHROUGH! It's a vital away goal and the substitute provides it! Dybala's stray pass is inexplicably sent into the path of a sprinting Pjaca, off the boot of Layun, and the Croatian makes no mistake, driving a sensational first-time finish into the bottom corner!
69'
Almost into the last 20 minutes now and it has to be said, this would be a big result for Porto. They would have liked to get a win to take back with them to Turin, but given the circumstances surrounding this match, a scoreless draw would be a real moral victory for them, denying Juventus the away goal.
67'
M. Pjaca enters the game and replaces J. Cuadrado.
Marko Pjaca is the first Juventus substitute of the evening as he comes on to replace Cuadrado.
65'
HOW CLOSE WAS THAT?! Good work from Khedira to win the ball in midfield before Higuain is eventually picked out higher up the pitch. The striker opens up as he cuts onto his right, but bends a strike agonisingly wide of the far post with Casillas rooted to his spot!
63'
STAT: Porto have only failed to score once in their last 12 Champions League games at the Dragao, it was against Dynamo Kiev in November 2015 (0-2).
61'
J. Corona enters the game and replaces Rúben Neves.
A second Porto change on the night sees Jesus Corona replace Neves, a positive switch indeed from the hosts, as Tiquinho will have a bit of support now.
60'
NOT FAR AWAY! A stunning hit there from Khedira, who got all of that effort on the half-volley, but just couldn't hit the target in the end as it was dipping and swerving the whole time, inches wide of the near post.
58'
The tempo is ramping up to high gear as we approach the hour mark. It's not just one-way traffic now, as Porto loosen the shackles a bit as they throw some caution to the wind. They've instilled a much more positive approach here as they chase a goal of their own to take with them back to Turin.
56'
Porto are being very brave here as they adopt a bit more urgency in the hopes of stealing the opener, and it's an admirable approach, but they're looking increasingly vulnerable as a result. They can't afford to leave themselves exposed like this.
54'
STRAIGHT AT CASILLAS! Again they threaten, and again they're denied! A punishing drive from Dybala once again from 25 yards, but it's right into the waiting arms of Casillas. The Argentine forward is really in the mood for a goal, and appears more than capable.
52'
STAT: Juventus are the only team to have won all three of their Champions League away games this season (8 goals scored, 1 conceded), their best ever run of victories on the road in the competition.
50'
S. Lichtsteiner gets yellow.
Lichtsteiner tries to win the ball in the Porto penalty area, and does arrive first, but he goes hard through Herrera, rather dangerously, on the follow through, and is booked as a result. A mocking cheer from the Porto fans rains down on the referee, who has actually done an expert job thus far.
48'
NOT FAR AWAY! A rare chance for Porto at the other end as Layun bends a delightful ball in towards the far post for his fellow countryman, but Herrera sends his header wide!
47'
OFFSIDE! Oh that's a big mistake there from the Juventus forwards! A delightful flick over the top from Pjanic sends Mandzukic through on goal, but he leaves it for Dybala, who smashes home an accomplished finish... only he was offside! Had Mandzukic taken the chance himself, the play would have been onside and Juventus would likely be ahead!
46'
Here we go again...
45' +3
HALF-TIME: PORTO 0-0 JUVENTUS.
45' +2
M. Pereira gets yellow.
ANOTHER BAD ONE! Maxi Pereira is lucky not to get his marching orders here as he obliterates Mandzukic with a tackle! The yellow is produced, but there really was a case for red.
45' +1
OFF THE POST! A superb strike, that, from Dybala! He takes one quick step to his left, before driving an effort back across goal from 25 yards that beats Casillas clean, but stays out off the woodwork! That close to an opener for Juventus.
44'
The duo of Felipe and Marcano are being given a real test tonight, but they have passed with flying colours thus far, not fading at all in the face of relentless Juventus pressure. They have done an excellent job of keeping things in front of them and limiting the visitors' looks at goal.
42'
STAT: Porto have kept a clean sheet in each of their last three Champions League games, the longest current run among all 16 teams left in this season’s competition.
40'
Brahimi's work rate is proving important for Porto as they fend off threat after threat. The hybrid midfielder-attacker is covering a lot of ground as he's consistently back to lend a hand in defence, while piecing together some decent, direct runs forward to provide little moments of respite for the defence.
38'
SMART SAVE! Excellent reactions and strong hands from Casillas to palm away Higuain's effort at the near post. Juventus pouring the pressure on here as they inch closer to a breakthrough.
36'
Porto desperately need to see this game into the half scoreless. There's no respite for them at the moment. Juventus are first to every ball and they have much more spring in their step. Porto are demoralised a bit. They need a rallying cry and something positive they can build off.
34'
GLANCED WIDE! Acres of space for Telles on the overlap, and all sorts of targets to aim at in the centre. He picks out the high-rising heading of Khedira, but the midfielder doesn't get the contact he desires as he sends a header glancing inches wide of the far post.
32'
STAT: Porto have lost only one of their 14 Champions League knockout games at home (W7 D6), it was against Manchester Utd in April 2009 (0-1).
30'
M. Layún enters the game and replaces André Silva.
Nuno Espirito Santo is forced into a change here, as Miguel Layun comes in to fill the vacant spot at left-back, with striker Andre Silva replaced. Tiquinho will be the lone man leading the line now.
29'
Well how does this change things now? Juventus, who were already in complete control of the match, are now full of life and confidence as they pepper the weakened Porto backline. This is going to be a real test of Porto's strength, fitness and character over the final hour of the match.
27'
Alex Telles gets a second yellow card and is sent off.
WHAT WAS HE THINKING?! Less than 90 seconds after picking up his first yellow card, Telles stupidly flies into another challenge on the flank, this time on Lichtsteiner, sending him hard to the ground. Porto players gather around the referee to plead for his leniency, but they really don't have a case. The full-back is sent off and Porto are down to 10 men!
25'
Alex Telles gets yellow.
A reckless and altogether needless challenge from Telles, who goes crashing through the back of Cuadrado on the halfway line. He will have to go up against the pace of the Colombian the rest of the night now on a yellow card.
23'
FIRST REAL CHANCE! Khedira and Higuain both flick the ball on smartly, as it falls kindly for Dybala on the edge of the box, but he skies his first-time effort with his weaker right foot! Had that been with his left, it might have produced the vital away goal Juventus crave.
22'
Casillas looks bright as ever though, which is a good sign for the visitors. Twice now he's come darting off his line to clear the danger, the latest intervention to see away the threat of Mandzukic, who was nearly slipped through on the end of some clever interplay.
20'
Porto are showing no inclination of trying to press high up the pitch, which has made for some very easy possession for the likes of Chiellini and Barzagli, while affording Lichtsteiner and Telles the luxury of getting forward with great regularity on the overlap.
18'
STAT: No Italian side has won any of their last five trips to Porto in the Champions League (4 draws followed by 1 loss). The last victory dates back to March 1993 (Porto 0-1 AC Milan).
16'
It's all Juventus for the time being, a drastic switch from the first 10 minutes where Porto were taking charge. The hosts have a lot of defensive minds in midfield and it's seen them drop a bit too deep off the ball, allowing Juve to get up the pitch with relative ease.
14'
ALMOST! Lovely running from Khedria, who shows good initiative to take on the Porto defence. He drives into the area and pulls it back for Higuain, but Marcano is just able to stick a foot out to divert it away from the striker's path, or he would have been through!
12'
Momentum has shifted a great deal now as Juventus are dictating the tempo here, enjoying the lion's share of possession. Porto have reverted into a defensive shell, but they're organising themselves quite well, which has made it difficult on the visitors to try and find a way through.
10'
Juventus seem to have weathered the early storm as they're beginning to knock the ball about with a bit more purpose and confidence. A nifty turn from Khedira sees him win a free-kick about 40 yards out, which Pjanic ambitiously strikes for goal, but he rattles his effort off the wall as the danger is averted.
8'
STAT: Andre Silva has been directly involved in two-thirds of Porto’s goals in this season’s Champions League (6 out of 9), scoring four and assisting two.
6'
Brahimi has a real strong ability from these set pieces and he gets the crowd going as he stands over to take this one, but can only let out a wry smile as he gets under his final effort, sending it over the bar.
5'
Plenty of possession for the hosts in the early stages as Juventus struggle to get a foothold in the match. Andre Silva makes a delightful run following a clever link-up with Tiquinho, and he wins a foul just outside the area following a foul by Chiellini - though the replays indicate it was a clear dive, and thus not the correct decision by the referee.
3'
A bright start from Porto sees them apply some early pressure, which only amplifies the noise in this stadium. It's far from a friendly atmosphere for Juventus, one which they will have to be sure to manage as the match progresses.
1'
AND THEY'RE OFF! Porto are in their black home strip as they get the game underway, attacking right to left, with Juventus in white and black.
Hello and welcome to live coverage from the Estadio Do Dragao in Portugal as the first leg of the Champions League round-of-16 draws to a close tonight when Porto hosts Italian champions Juventus!
Yesterday’s excitement has set the scene for what should be another wildly entertaining night of Champions League football between a pair of white-hot teams in Porto and Juventus, having won six and seven successive matches, respectively, entering tonight’s clash.
After stumbling through their opening two matches in this season’s competition proper, Porto turned their campaign around, going four matches unbeaten, winning three and conceding just one goal, to close out the group stage in second spot, behind Leicester City.
Porto’s surge in form on the continental scene has resulted in domestic success as they cut Benfica’s lead atop the Portuguese Primeira to just one point – though the standard for domestic dominance has been set by their opponents tonight, Juventus.
Massimiliano Allegri’s side cruised to first place in their Champions League group, all the while maintaining their impressive form in the league, building a seven-point cushion at the top as they pursue a sixth successive Serie A title – though the aim this season will be to end a 20-year hiatus on lifting a trophy in Europe.
CONFIRMED TEAM NEWS:
PORTO (4-4-2): Casillas; Maxi, Felipe, Marcano, Telles; Herrera, Danilo, Neves, Brahimi; Andre Silva, Tiquinho.
SUBS: Boly, Sa, Corona, Jota, Andre, Layun, Oliver.
Nuno Espirito Santo has adopted a cautious approach to tonight's match with the defence-minded trio of Ruben Neves, Danilo Pereira and Hector Herrera all in the starting XI, ahead of Jesus Corona, Oliver Torres and Diego Jota. Danilo will drop deeper in midfield, but figures to have plenty of support in Neves and Herrera, with Yacine Brahimi on hand to offer a link between midfield and attack.
Massimiliano Allegri rotated his squad for Friday's victory over lowly Palermo, resting many of his regulars, with Sami Khedira, Paulo Dybala and Gonzalo Higuain the only outfield players to keep their place. Mario Mandzukic and Juan Cuadrado are restored to support Higuain with Miralem Pjanic partnering Khedira. Andrea Barzagli and Giorgio Chiellini start in defence with Leonardo Bonucci left out of the squad as punishment, following an argument with manager Allegri during Friday's match.
Juventus well on top, despite what the score may indicate, as we're through 45 minutes at the Estadio Do Dragao. Porto have their work cut out for them, down a man following the sending off of left-back Alex Telles for two senseless challenges in the space of 90 seconds. Juventus have pressed hard for the breakthrough, but they have been denied so far by Iker Casillas and the woodwork.
Marko Pjaca and Dani Alves came off the bench to score two minutes apart as the Bianconeri cruise past 10-man Porto, taking a commanding lead back with them to Turin. Alex Telles' sending off after 27 minutes proved to be Porto's undoing in the end as their resistance was finally broken, with Juventus taking a massive step towards the quarter-finals.
That's all for our live coverage, thanks for following along. Goodbye!
