Good evening. It’s Champions League time again and tonight sees Juventus try and overturn a 2-1 deficit against Porto with a place in the quarter-finals at stake. I’ll bring you plenty of build-up before the game kicks off, and then full live coverage from 20:00. It should be a good one!

A goal either way will win this and you can sense the nervous energy building out on the pitch in Turin.

We are under 20 minutes from extra-time. But you suspect there will be chances for Juve to win it before the 90 is up.

Diaz comes on as Porto try and freshen things up. It's going to be counter-attacks that are the visitors' only realisitic source of threat for the remainder of the game, judging from how it's gone since the red card.

It’s been an absolute blinder of a game this, but you have to feel a bit for Porto. They are camped deep in their own half now, stunned by that two-goal salvo and with just ten men to try and rescue the tie.

Well, well, well. What a start to the second half that has been for Juventus. You’d put good money on them going through from here, and if they do then they have Chiesa to thank for pulling them right back into the tie.

GOOOAAALLL!!! It’s Chiesa again and Juventus are level. The 23-year-old makes no mistake as the ball drops to him in the box, bagging his third of the tie to make it 3-3 on aggregate against ten-man Porto.

Should be two for Juve as Chiesa goes clean through but is put off by Pepe with the goal gaping and the ball comes back off the post. What a chance!

Off! It’s a second yellow for Taremi in a matter of moments and Porto are down to ten men. The forward kicked the ball away and it probably was a yellow by the book, but it’s a gut-punch for Porto.

Taremi goes into the book for a foul on the goalscorer Chiesa in midfield. That’s a little on the harsh side, although the Juve man’s reaction did put plenty of pressure on the referee to make the decision.

Well that’s made things interesting! It’s the first significant involvement for Ronaldo on the night and it’s led directly to a goal that gives Juve hope.

GOOOAAALLL!!! Juventus have one back and it’s Chiesa who’s got it, curled into the far top corner after a good run and lay-off by Ronaldo. 1-1!

Away we go again. It’s a bit dramatic to say that Juventus have 45 minutes to save their season… but it’s not far off the truth!

The half-time whistle goes and Juventus have some serious work to do if they are to avoid a Champions League exit tonight. Porto are well worth their lead on the night after an impressive counter-attacking display, and as it stands Juventus need two goals to even get back on level pegging in the tie.

Oliveira pings a shot towards goal but it’s a reasonably comfortable save for Szczesny. We’re into four minutes of added time at the end of the half.

Ronaldo gesticulates as another long ball goes nowhere near him and his cleared. The service for him tonight has been pretty poor so far.

Here come Porto again on the break, but Szczesny comes well out of his box to meet a long ball on the volley and clear. He’s a confident guy the former Arsenal man, you’ve got to give him that.
