Rezaa Sait: Emery out. Regardless of the red card, his substitutions has been horrific and his treatment of Suarez even more.
Joe Wedgewood: Auba off? Arsenal lack quality but Unai consistently drops Auba, Ozil, Laca and Ramsey. Odd. No clear plan.
Colin Hines: This Arsenal scoreline tells you the real story about where this club is. Absolutely mediocre everywhere.
Rennes 3-1 Arsenal
All over! Excellent game, Rennes were excellent, they get an excellent win.
Excellent stuff.

Adam Dean: Why is Monreal so far up the pitch when we have 2 minutes left and down to 10 men?
Karl: No good having everyone behind the ball, if you can't defend, no plan B Arsenal
Mark: No disrespect to Rennes, but a half decent team would brush them aside. Unfortunately, Arsenal aren't a half decent team. They'll still turn it around at home, though.
Rennes 3-1 Arsenal
Arsenal will have work to do now in the second leg. That goal is right up there with my favourites this week. A belter.

Matthew Irwin: Just like the Arsenal player the fans aren't giving this Rennes side enough respect, remember they're only after knocking out a Betis side filled with big name
Carl: You can slate Emery all you like, but actually the damage limitation is the best thing Arsenal can do at the moment, instead of going down to a further third goal. Take it back to the Emirates a goal down; that's a good move by Emery
Javel Bleach: Oh.My.Word!!! What a goal!!
Ismaila Sarr
BRILLIANT goal!
Give me a powerful header on a great cross any day of the week and that is an absolute beauty! James Lea Siliki sweeps over a booming ball from the left, curling away from Petr Cech and there's Ismaila Sarr arriving at the back post to plant a diving header into the corner.
Just a dream of a ball that demanded to be put away and Sarr did the business!

Dries De Coster: Forget Parc de Princes from yesterday... this is Parc de Bus from Arsenal
Prince C Nnaji: Trust Emery! He’s won this trophy three times.
Not Jamesy: Tonight Arsenal have Scored against Arsenal
Rennes 2-1 Arsenal
Granit Xhaka is absolutely pelted as he goes over to take a corner for Arsenal, it's nothing too sinister though, just scrunched up balls of paper from the tifo the fans made before kick-off. Not sure Uefa will like that though. Into the last few minutes, Unai Emery and co hoping to slope back home with a not too damaging 2-1 defeat in their hand luggage.

Arsenal down to 10 men, but no clear change in tactics. Yesterday United changed their tactics at least twice to counter PSG. Contrast between Emery and Solskjaer is obvious. I know who I prefer.

Rennes 2-1 Arsenal
Arsenal are playing a 4-5-0 which is a new one on me. Everyone behind the ball.

Two very lucky goals for Rennes
Chris, London
Struggle to understand Emery at times - Ramsey for Iwobi best move - crazy red card though
Paul, London
Rennes 2-1 Arsenal
There's shutting up shop, and then there's concreting over the whole entrance. Arsenal replace Pierre-Emerick Aubameyang with Sead Kolasinac, leaving Aaron Ramsey as the furthest man forward.
Aubameyang is NOT happy on the bench.

Silvio de Fede: Remember when Arsenal (like 15 years ago, with Vieira & Co.) was a great fighting team? I miss that. This team is pitifully soft, this has been a disastrous second half till now. And Emery isn't the right manager to change that. We need someone like Antonio Conte

If Ismaila Sarr wasn't being watched by Premier League scouts already he soon will be. What an absolute menace down the right wing, giving Nacho Monreal an awful time. Just the final product that needs improving. Can Rennes get a third?

Scott: Arsenal doing their best PSG impression.
Paul: Arsenal will turn this around at home. Won't win the Europa League though.
Abdul Said: Arsenal are making this Rennes team look like Barcelona
Only one goal elsewhere since the break, Gerard Moreno putting Villarreal 2-1 up at Zenit St Petersburg.
Eintracht Frankfurt manager Adi Hutter was sent off for kicking a water bottle after his side were denied a penalty against Inter Milan. Still 0-0 in Germany.
Rennes 2-1 Arsenal
Arsenal turned a first-leg defeat around against Borisov and they may have to do it again. In fact, if they get out of here with a 2-1 defeat they should count that as a job half done.
Rennes look like scoring with every attack. Henrikh Mkhitaryan may be about to do the impossible and make Eric Bailly look like only the second worst makeshift right-back I've seen this week.

Vincent Wood: Well that wasn’t predictable now was it
Chris Clarke: What a joke we look: no ideas, no cohesion. Ten men or no, this is appalling. They’ll score at least one more
Rennes 2-1 Arsenal
Petr Cech has to make another save from Hatem ben Arfa, really enjoying himself, as Arsenal fall to bits at the back again - it's an escape. Mesut Ozil is then replaced by Aaron Ramsey.

Ramy Bensebaini now ploughs upfield from left-back and screws a shot wide, off his toes a touch. Arsenal taking heavy damage but then they nearly score a brilliant goal of their own!Their first attack in ages, Matteo Guendouzi finds space on the left, he finds Mesut Ozil, who spins inside the area, links up with Pierre-Emerick Aubameyang and then gets a shot away but it's tame.
