67 mins: Chance! PSG think they have a penalty after Ousmane Dembele is brought down by Mats Hummels. The referee initially points to the spot before awarding a free kick on the edge of the box.

VAR looks at the incident and agrees that the contact was outside the penalty area. Marco Asencio takes the set piece but hits the wall and Dortmund work it clear.

66 mins: Bradley Barcola and Marco Asencio are brought on to replace Fabian Ruiz and Goncalo Ramos for PSG. Barcola’s first involvement is to kick start a counter-attack.

Marcel Sabitzer pulls him down cynically and earns himself a yellow card.

64 mins: Post! Nuno Mendes is the latest Paris Saint-Germain player to strike the woodwork.

It’s a blistering shot from the left side of the pitch and Gregor Kobel is beaten. Dortmund are spared some blushes by the upright though which rebounds the ball back into play.

61 mins: Close! Vitinha drifts into space on the inside right channel where he picks up the ball. A positive run takes him into the penalty area who he squares the ball to Goncalo Ramos.

The forward shoots and smokes his effort over the crossbar!

60 mins: An hour played and this evening isn’t going at all the way PSG would have hoped for beforehand. The fans are keeping the spirits up though and the atmosphere remains electrifying.

They’re trying to move the ball with pace and precision but it’s tough against a Dortmund side that now have a cushion and are content out of possession.

57 mins: Marco Reus, who is leaving Borussia Dortmund at the end of the season, comes on to replace Karim Adeyemi in the middle of the pitch.

The experienced midfielder is being brought on to see out this game and ensure they secure their spot in the Champions League final.

54 mins: That goal from Hummels, who has been defensive solid over both legs so far, could just send his team into the Champions League final.

Just a minute or so after PSG hit the post, Dortmund have broken the deadlock and are now two goals ahead. One more and this semi-final will be over.

50 mins: There it is!

The ball is swung into the box from a corner and comes curling onto the head of Mats Hummels. He shoves Lucas Beraldo to gain half a yard of space before leaping and powering a header into the back of the net!

49 mins: That move from PSG was the best of the night and the host should really be level in the tie. Over the two legs so far PSG have hit the woodwork three times.

Dortmund need to press higher. A goal for them would surely settle their nerves.

48 mins: Nearly! Goncalo Ramos slips to the edge of the box and releases the ball out to Achraf Hakimi who sidefoots an effort across the goal and watches it get turned out for a corner.

PSG play it short to Dembele and quickly whip it into the box. It comes out to the back post again where Warren Zaire-Emery belts his effort into the nearest post!
