PSG have time to take the corner but Chelsea deal with it and that will be that.
Paris Saint-Germain 1-1 Chelsea
Shakhtar Donetsk 0-0 Bayern Munich
Courtois saves Chelsea again! Pastore swings an exceptional cross into the box from the left that Ibrahimovic meets with a downwards header. It's goalbound, but the Belgian 'keeper gets a palm to it and makes the save.
All PSG in these final few minutes. Again, Matuidi almost battles his way from the left but Chelsea survive again.
Three minutes of normal time remain of the first leg.
Pastore chases down an over hit cross field ball and hooks a cross back across to the far post where Cavani attempts an outrageous scissor kick. It's an awfully difficult one, though, and he can only connect with fresh Parisian air. Van der Wiel retrieves the ball out on the right but he is quickly crowded by blue shirts.
Pastore's first contribution is to curl a hopeful effort well wide of the goal.
Javier Pastore enters the fray to replace Lavezzi. Moments ago Chelsea brought on Juan Cuadrado for his Champions League debut, replacing Willian.
Cavani almost makes it two! On the left-side of the box, Cavani plays a neat one two and jinks past Matic with ease. He tries to toe one into the far corner from a very tight angle but can't find the inside of the post.
Willian has space to run into down the right but is dutifully tracked by his marker and is forced to turn back to Ivanovic. He cuts inside and tries the other route until he is clumsily tripped by Luiz. Chelsea have a free kick, but fail to trouble anyone with it.
And Luiz drives it into the wall. PSG keep it alive however and shift play down the left where Maxwell swings in a delicious cross, but Lavezzi can't quite stretch high enough to connect with a header.
Fabregas, whose looked a bit knackered all game really, catches, Matuidi with a weary-looking challenge about 25 yards out from goal. David Luiz (!) stands over it...
Lavezzi wastes a corner for PSG and van der Wiel follows it up by flinging an aimless ball into the box that Courtois easily collects. It's all gone a bit scrappy, these past five minutes.
It is still goalless in our other game this evening but Bayern Munich are down to 10 men after Xabi Alonso was shown his second yellow of the evening. Not quite the way he thought he'd be celebrating his 100th Champions League game, I bet.
Courtois is forced to palm Luiz's deflected header over the bar from Lavezzi's free kick. PSG get the corner, but it's easy for Courtois.
David Luiz races across to the touchline to block Costa and stick his mush into the face of the Chelsea striker's. Luiz is fishing, Costa could end up biting before the end of the night.
Chelsea hanging on here! Terry does well to clear the danger but then Hazard's stray pass is pounced upon by Matuidi. He leaves it to Ibrahimovic, whose deftly plays a sublime one-two with Lavezzi before driving past Cahill and taking a shot on from inside the area. Courtois stops it, and John Terry is in the way to block Lavezzi's follow up effort off the line!
Van der Wiel swings in another dangerous cross from the right but Terry is there just before Cavani.
Chelsea respond by winning a corner but do little with it ans PSG can counter through Maxwell. They could of, I should say, the Brazilian slips and Ivanovic is across to intercept before David Luiz smashes the ball away from his former teammate.
PSG are level! It's a brilliantly simple goal. Maxwell jogs down the left, slides the ball on for the onrushing Matuidi who sweeps a sublime cross into the box where an unmarked Cavani directs a header into the bottom corner. Easy stuff, but Chelsea's marking was all over the gaff, there.
Goal! PSG 1-1 Chelsea (Edinson Cavani, 54)
Verratti commits two niggly fouls in quick succession. He avoided a booking in the first half, but it won't be much longer before he picks up one in this.
Maxwell cuts in from the left, plays the ball to Verratti and gets it back via a wonderful flick from the Italian. The Brazilian is stopped in his tracks, but Verratti picks the ball up again and tries to jink his way up the byline. He evades one challenge, but takes on one too many and is dispossessed.
And we are back underway for the second half.
Paris Saint-Germain 0-1 Chelsea
