Merino in the 50th minute actually managed to put the ball into the PSG goal. However, based on the VAR review, the goal was disallowed and then declared no goal. This gave disappointment to the players, but this is what happened. This happened because Trossard was offside.
This is certainly very unfortunate, because unfortunately, Trossard's position is a few inches ahead, so this will be an evaluation for Arteta in the future.

It was quite unfortunate that Arsenal's return goal had to be canceled due to offside. And actually in the second half Arsenal started to be able to make more pressing attacks into the PSG defense area, which means this team has started to understand PSG's playing patterns. And maybe in the second leg Arteta can come up with a better strategy to penetrate PSG's defense. It's just that we can understand that Arsenal were not optimal in this match because there are still several important players who are injured and absent for quite a long time. So Arteta can only maximize what he has. PSG this season really has a more open style of play. And they succeeded with that style of play. But if Arsenal plays in optimal condition then I think Arsenal can be better. Unfortunately, Arsenal were not able to play optimally in this match. And I actually have doubts about the second leg. And if Arsenal fail to come back this season then that would really be a shame. And I feel quite sorry for Arteta. Because he built a team well but he always failed at important moments.This is certainly very unfortunate, because unfortunately, Trossard's position is a few inches ahead, so this will be an evaluation for Arteta in the future.
