The advantage is on the side of PSG but do a 1:0 defeat look scary for a team like Arsenal that eliminated the Champions?Arsenal looks all ready and prepared against PSG and honestly, a comeback is underway and if care is not taken, PSG might find it difficult to play confidently as they did in the first leg.
You saying Arsenal are prepared for PSG in the second leg of the match, and you think PSG also are not prepared to play against Arsenal? PSG are already ahead of Arsenal with a goal which is an advantage for PSG, the second leg will be kind of difficult for the two teams, but I don’t see anything that will make PSG lose confidence in the second leg of the match, and I will say Arsenal will be finding it difficult to get a win in the second leg of the match, because PSG will want to stop them. PSG will be fighting for either a win or draw in the match, and Arsenal will have to get a win in the match if they wan to qualify to the final.
