Good evening and welcome to Eurosport's LIVE text commentary of Porto vs Juventus in the first leg of a last 16 Champions League encounter. Team news to follow... Kick-off 19:45 GMT.

FULL-TIME! Juventus will take a two goal lead into the second-leg of this last 16 Champions League tie. Second-half goals from Pjaca and Alves are the difference against a stubborn Porto side who played over an hour with only 10 men.

Only two minutes will be added on at the end of this one.

Frustration creeping in at the dying stages for Porto as Marcano trips Higuain and is subsequently booked.

CLOSE! Khedira is slipped through on goal and he dinks the ball over Casillas but it flashes inches wide of the goal.

JUVENTUS SUB: Final change for the visitors, Dybala is replaced by Claudio Marchisio.

Juventus deal with the set piece well and then immediately launch a counter attack which Herrera does well to stop as he cynically takes down Pjaca and receives a booking.

Porto have only failed to score once in their last 12 Champions League games at the Dragao, against Dynamo Kiev in November 2015 (0-2)... and now they win a corner.

Into the final 10 minutes and Juventus look in no mood to settle for two goals. A third would completely kill this tie as a contest.

The set-piece comes to nothing. The camera flashes to Porto's manager Nuno Espírito Santo who simply looks dejected. He will have strong words with Telles Alex tonight, one would imagine...

Juventus continue to pile the pressure on the hosts in search of a third away goal as Pjanic forces a corner.

All credit must go to Allegri whose substitutes both score almost immediately after coming on. Porto now have a mountain to climb, can they find a goal back against one of the best defences in world football?

Two goals in two minutes for Juventus who finally make their extra man advantage count.

GOAL! Dani Alves seals the game for Juventus with his first contribution! Alex Sandro picks the substitute out at the back post, Alves controls it on his chest and guides it past Casillas.

JUVENTUS SUB: Lichtsteiner is replaced by Dani Alves.

Third and final sub for Porto - Diogo Jota is on for Brahimi.

GOAL - Juventus are ahead! Pjaca breaks 10-man Porto's resistance. Dybala's pass bounces off the shin of a Porto defender and the ball falls kindly to the Juventus sub who scores with his first touch!

Brahimi has the beating of Barzagli but he over runs the ball at the byline and it goes out of play for a goal-kick. Still, it wastes a little more time for Porto.

JUVENTUS SUB: The visitors make their first change, Marko Pjaca replacing Cuadrado.

GREAT CHANCE! Typically Higuain almost opens the scoring! He turns two defenders the wrong way, cuts in and curls the ball agonisingly wide.

It hasn't been the most exciting games, it has to be said. You feel 10-man Porto are happy to take a goalless draw while Juventus are struggling to create anything of note.
