Congratulations to PSG for their victory, the next match will be more difficult for Arsenal because they will play at PSG home, they have to train harder, improve their game patterns and coordination between players if they want to win in the upcoming match.
I don't think the home advantage will count for anything. PSG dominated the game in the first twenty minutes. Arsenal grew into the game and dominated the second half. They should be able to take that positive to the second leg in France and put pressure on PSG from kickoff.
A one-goal lead is very easy to recover from; the boys do not need to lose their heads.
Declan Rice did not have that freedom of being able to run forward because of Partey's absence. With Partey in the second leg, Arsenal has got a better chance.
