There are some friends who are very confident that Arsenal will win today. But it may not be up to your expectations. Even I was quite surprised to see the play of Dembele and friends. They are very different, even the EPL's fast style of play does not seem to cope with PSG's possession. PSG played effectively with one or two touches. In fact, I read in the media that Arteta also admitted that PSG's game was extraordinary.
Maybe PSG's 1-goal difference is not big, there is still a chance for Arsenal to catch up in France. But if you look at the pattern of play today and there is no change for Arsenal I think it will be more difficult. I'm sure there are still opportunities because UCL always presents surprises. But remember leg 2 is diferent because Arsenal goes to France and i think many preasure from a lot suporters.
The ball possession statistics show that both teams were good in the use of the ball. But I thought the host had a better midfield but the visitors were outstanding there. Arsenal really felt the absence of Thomas Partey. He is the engine room of the team; I guess his replacement didn't function like him. Arsenal will be glad that his suspension has ended, and he will be present in the return leg. With the return of the Ghanaian professional footballer, PSG would have to be ready for a big fight.
