Arsenal hosted PSG at home in the Champions League semi-final first leg.Arsenal didn't play very well and lost in this match.PSG got an important away win with a goal scored by Ousmane Dembele in the 4th minute.PSG is likely to eliminate Arsenal with this advantageous score. I expected Arsenal to win against them, but I don't think they played the game they wanted to.With Liverpool already the champions in the league, they need to put all their focus here.This may be a troubling score, but it is not impossible to turn it around.They still have a chance to get through the round with a better game away.
