As I predicted PSG is stronger than Arsenal, but I thought the first leg Arsenal will not lose (either Arsenal win or draw), since they lose, it means they're bad. Donnarumma made many great saves, few good chances Arsenal made not enough to break the defense. Where's Rice? oh it's already rotten!
Dembele is injured, but I think PSG will be fine because they still have many high quality players.
Maybe Arteta's confidence after the win was a bit strong, that they can beat any team. As yesterday's match with PSG showed, beating anyone is not that easy. Yes, Donnarumma played very well yesterday, he made a lot of saves and definitely saved PSG from a goal. But on the other hand, yesterday I said that I think PSG is a stronger team and I expected them to win this match. And in the return match, I think that PSG will also have the advantage, because they can show an even better game at home. Dembele's injury is very bad, I hope that he recovers quickly and returns to the game.
