Ousmane Dembele will be available to face Arsenal tomorrow.
"He's trained with us for two days in a row, so he'll be ready to play", Luis Enrique
This is good news for PSG and bad news for Arsenal
Don't judge it immediately because it is still not necessarily good news for PSG or bad news for Arsenal because PSG still have to do everything to keep winning at home in the second leg. Because winning with an aggregate of one goal is still not necessarily safe for PSG so it is not only Dembele who must play well in the second leg of the semi-final because all PSG players must be able to give their best performance in the match tomorrow.
It is true that football is not a game of one man, but of eleven. So, for a team to win, a team performance is a must. The addition of one player to the team is not good news for PSG, because they have not yet won a semi-final. Similarly, Ousmane Dembele playing against Arsenal is not bad news for Arsenal. Because Arsenal will have to play against eleven men, maybe something will be different.
PSG is not yet at a stage where their semi-final is guaranteed. They are only 1 goal ahead, which may not be a long time to pay off. It is not possible to say anything until the end of tomorrow's match, because Arsenal have already defeated Real Madrid at home. In other words, playing at PSG's home does not mean that Arsenal will not be able to play well. They are capable of performing at the opponent's home field as well, which they have already proven.
