Arsenal were a complete failure tonight. It was the summary of the match. Martinelli... He was a hopeless case. I couldn't count how many chances he wasted after a point. I wonder why Arteta insisted on keeping him in the match anyway.

Congrats to PSG! They have opened the door slightly for the finale. They were too comfortable with keeping their opponent under pressure for most part of the match. If they keep this up home too then there is no obstacle for them to take their chances with the trophy.
Like seriously? Where you expecting Arsenal to knock off PSG just like that? I was hoping they do that but I never expected it because the chance was small, no way they can do that like it a simple game when PSG hasn't never had it fair, they ball hard and kick any team that comes there way and so Arsenal are going to eventually at the second leg unless football happen but like I said, the chance is small and it will cost them alot even if they try.
This second leg isn't going to be difficult for Arsenal if at all they didn't concede any goal at emirate but because they did, it is going to be difficult for Arsenal. This was exactly what Dortmund did and were thinking it was going to be easy but instead they got whoop in the ass and never qualified but that was even their own home but this is PSG home, only Arteta understand how he plans to win the second leg but it's going to be very difficult.
You're right, PSG is a tough opponent, and Arsenal had a slim chance to begin with. The away goal puts Arsenal in a difficult position for the second leg, especially with PSG's strength at home. It's going to be a tough mountain to climb, but if anyone can pull off an upset, it’s Arsenal. Arteta will need to come up with something extraordinary to turn it around, but PSG have the advantage.
