- Domenico Criscito sent off for Zenit in 90th minute.
- Jonas Oliveira heads home stoppage time winner from Nicolas Gaitan free-kick.
Paris Saint Germain 2-1 Chelsea
- Zlatan Ibrahimovic gives hosts lead with deflected free-kick.
- John Obi Mikel levels with sixth Chelsea goal in 10 years.
- Substitute Edinson Cavani gives PSG first leg lead with goals 12 minutes from time.
Full time in both of our last 16 first legs and drama, in the end, in both matches. PSG will take a narrow lead to Chelsea after substitute Edinson Cavani struck with 12 minutes left to give the French champions the advantage. John Obi Mikel had earlier cancelled out Zlatan Ibrahimovic's free-kick.
In Lisbon, a game which meandered aimlessly towards a goalless draw was illuminated in stoppage time. First as Crisito was dismissed for Zenit for a second booking and from the subsequent free-kick, Jonas headed home the winner which gives Andre Villas-Boas' side must to do in the second leg.
Well that brings an end to the first of our Champions League live text offering. We're back tomorrow with Roma vs Real Madrid and Gent vs Wolfsburg, but until then goodbye.
Full time: Benfica 1-0 Zenit
Full time: PSG 2-1 Chelsea
Goal: Benfica 1-0 Zenit (Jonas)
Benfica take advantage of the numerical supremacy immediately. Gaitan plays the free-kick in and Jonas leaps and heads into the corner. How vital a goal in a tie with few chances, could that be? Villas-Boas looks ready to burst.
Red card: Crisito (Zenit)
Some action of sorts as Zenit are reduced to ten men in stoppage time as Crisito is dismissed for a second booking. Will it make a difference?
Gary Cahill prevents Marquinhos making it three as he blocks his effort behind. Chelsea will surely be content even if they have conceded late on. Any chance of grabbing an equaliser looks all but dead though after Willian curls a free-kick straight to Trapp.
Goal: PSG 2-1 Chelsea (Edinson Cavani)
Barely on the field three minutes, Edinson Cavani thrusts PSG back ahead. Di Maria lofts a ball over the top to find the Uruguayan who shoots hard and low through Courtois' legs and into the back of the net. Killer blow for the hosts.
Chelsea threaten for the first time in what seems like a while as he escapes Marquinhos and it takes Trapp to come off his line to deny the Brazilian. Just 13 minutes left; can either side force a winner?
Edinson Cavani on for Lucas Moura now for PSG. Blanc going for the win.
Benfica turning the screw now and the knock down finds Jardel but the defender can't wrap his foot around the ball and is flies just wide from just seven yards.
Which comes to nothing. Willian's ball is headed away by David Luiz.
Oscar on for Eden Hazard in Paris. Yellow cards for David Luiz and Lucas Moura. And a free-kick for Chelsea 30 yards from goal.
By a long, long way Benfica force the best chance of the game at the Stadium of Light. Gaitan ghosts past one defender and his shot is brilliantly saved by Lodygin before the rebound is skied over the bar.
Angel di Maria over a 20-yard free-kick and he curls it around the ball but Courtois, two-handed, pushes the ball away.
Chelsea throwing everything in front of PSG efforts on goal now. Ibrahimovic seems certain to score but he miscues a header and the loose ball is thundered goalwards by Matuidi but a combination of Ivanovic and Cahill keeps the scores level.
Thibaut Courtois showing his worth tonight and he makes the pick of his saves tonight to deny Lucas, getting down well to his right to keep out the Brazilian. The game has swung back the way of the Ligue 1 leaders.
Javi Garcia booked for Zenit for deliberate handball and he too will miss the second leg. Replays suggest he knew very little about it though. Looks like the official caved to the crowd on that one.
Di Maria slips the ball inside Pedro to Maxwell but Gary Cahill is to the rescue. Chance for Benfica but Ezequiel Garay lashes his shot fully 10 yards wide. Not a great effort from the inside left channel.
PSG coming back into the game as an attacking force and Ibrahimovic's effort is turned away by Courtois, who has been in the fine fettle tonight.
Chances at both end as Di Maria forces a fine save out of Courtois. In Lisbon meanwhile, a rare moment of attacking intent from Zenit as Witsel's effort is kept out by Julio Cesar.
Trapp continues to prevail in the one-one-one duels with Diego Costa, denying the Spaniard as he comes out after Willian threaded a pass through.
Verratti and Hazard both down in a heap after an aerial challenge, with replays showing there was a loose elbow thrown by the Belgian, though accidentally. Play back under way.
Players out for the second halves in Paris and Lisbon. Can these four teams lay down a market ahead of the second legs?
Half time: PSG 1-1 Chelsea
Half time: Benfica 0-0 Zenit
Varying entertaining in two of the finest cities in Europe. In Paris, it is advantage Chelsea after Jon Obi Mikel cancels out Zlatan Ibrahimovic's free-kick, which had deflected in off the Nigerian.
The less said about events in Lisbon, the better. Benfica and Zenit - playing their first match for two months - have served up a game hardly fitting of the illustrious stage. Neither side have threatened the scores in this one. Must try harder.
