It's back! Hello and welcome to LIVE coverage of the matchday one Champions League Group A clash between PSG and Arsenal at the Parc des Princes. Both sides have had mixed starts to 16-17 with their respective managers come under the spotlight. A win here will give one a real lift, while that glare will only intensify for the loser... It's a big night that pits two heavyweights against each other and it all gets underway at 19.45 BST. Team news next.

FT: PSG 1-1 Arsenal. Alexis Sanchez struck late to rescue Arsenal as they secured a fortunate 1-1 draw at Paris Saint Germain in their Champions League Group A opener. Edinson Cavani gave the hosts an early lead but then wasted a series of chances to seal the triumph. The teams finished with 10-men as Verratti and Giroud saw red for second yellows while Ospina shone in goal for the Gunners to justify Wenger's decision to drop Cech. This is a great result for Arsenal in what is surely their most difficult fixture in Group A.

CLOSE! Marquinhos somehow fails to convert at the far post after Di Maria's right-wing corner had been flicked on!

Didn't seem like much in the challenge...

TWO MEN OFF! A crazy finale! Giroud and Veratti both pick up second yellows and the teams will each finish with 10 men.

Motta booked for a foul on Giroud.

No real pressure from the hosts. They look a bit lost now. Arsenal playing time down.

Four minutes added. Can PSG find a winner?

UPDATE: Seventh heaven for Barca against Celtic...

Giroud booked.

This will be a superb result for Arsenal if they can hold on here.

Infostrada stat: Sanchez scored his first CL away goal for Arsenal in his seventh away appearance for the club. His last CL away goal came almost four years ago, on 2 October 2012, when Barcelona won 2-0 at Benfica.

ARSENAL CHANGE: Elneny on for Ozil. Wenger hoping to see this out.

PSG CHANGE: Aurier off, Meunier on.

It's all happening now. End to end. Iwobi with a chance on the left of the area but Areola makes a decent stop to keep it out.

Exactly!

Ospina produces more heroics! Cavani tries to round the keeper in the area but the Colombian gets a fine touch on it to divert it to safety.

PSG CHANGE: Krychowiak off, Pastore on.

Arsenal very fortunate to still be in this. PSG and Cavani in particular only have themselves to blame.
