PSG's Ousmane Dembele scored a crucial goal in the fourth minute, giving his team a significant advantage. However, Henry pointed out that PSG's performance dropped off after Dembele was substituted out of the game.
This allowed Arsenal to gain more control and put pressure on the French team. Henry emphasized that a lot needs to change for Arsenal to win the second leg in Paris, but he still believes anything can happen in the tie.
Henry's comments suggest that the tie is far from over and that Arsenal still have a chance to make a comeback.
