Good evening and welcome to Eurosport's LIVE text commentary of the first-leg last 16 Champions League tie involving Benfica and Dortmund at Estádio da Luz. Team news to follow. Kick-off: 19:45.

FULL-TIME! Kostas Mitroglou's goal on 48 minutes proves to be the difference as Benfica earn a 1-0 victory over Dortmund! A night to forget for Thomas Tuchel and Pierre-Emerick Aubameyang, who missed a penalty.

There's a foul on the goalkeeper and Benfica will take their time with the free-kick.

Semedo heads clear from Dembele's cross but the ball is pumped back into the Benfica penalty area and Dortmund win a corner... The hosts are running on empty at the moment!

FOUR minutes of added on time to play!

Dortmund win a corner which Dembele takes... it's cleared to the edge of the area but Pulisic's shot doesn't trouble Ederson. One minute of normal time to play.

There's some tired legs out there now but Benfica are hanging on. Dortmund have three minutes to find an away goal.

YELLOW CARD! Dortmund's frustration are increasingly evident now as Pulisic is booked.

GREAT SAVE! Ederson is the hero again as his reaction save denies Pulisic's deflected half-volley from range!

DOUBLE DORTMUND SUB! A big call from Thomas Tuchel as he brings on Christian Pulisic and Gonzalo Castrol in place of Reus and Guerrerio for the remaining minutes.

You'd imagine Thomas Tuchel and his side would snap your hand off for a 1-1 draw to take into the second-leg but Dortmund haven't looked like scoring in quite some time now.

Benfica have dropped incredibly deep as they try desperately to hold onto their one goal lead.

A superb tackle from Luisao takes the ball away from Schurrle inside the area. Thomas Tuchel shows his desperation as he appeals for a penalty!

His goal still separates the sides as we enter the final 15 minutes of the contest...

BENFICA SUB: Third and final change for the hosts as goalscorer Mitroglou is replaced by Raul Jimenez.

YELLOW CARD! Schmelzer takes one for the team as he hacks down Salvio and the referee has no choice other than to book the Dortmund captain.

Reus is crowded out in the penalty area and Benfica hack the ball clear but it's straight back to the visitors whose pressure is relentless at the moment.

GOAL UPDATE: Quite incredibly, PSG are now beating Barcelona 4-0 as Edinson Cavani gets in on the rout.

Benfica are holding their shape well as they continue to frustrate Dortmund who eventually lose the ball.

CLOSE! The visitors continue to dominate the game but STILL they await an opening goal. Dembele's corner picks out Papastathopoulos who head wide.
