If Pep does it, then Man City will win. But if Pep doesn't give his players strong motivation, Man City is currently in a slump.
PSG and Man City are both in a difficult position right now. They have to fight to bring each other down. Even if they share points, their position in the Champions League standings will not be good.
I still hope Man City will win and qualify for the knockout round. I believe they can still compete in the next round. But if PSG wins, maybe Man City will lose their chance to qualify.
I think it goes without saying, because one of the coach's duties is to motivate his players, so without us talking about it I'm sure every coach will do that, especially when they realize that they are not in a good condition because they have received many unsatisfactory results. This is a match like a life and death match for both clubs, so they will do their best in a crucial match like this. What I hope is that this match will be very entertaining, and actually I don't see who will win, because I want to see the match go very interestingly.
