Of course, both clubs will take the match very serious but the club that can outsmart the other will definitely win the game. I can't say which of these club is the strongest because City has been a mess to themselves recently, and they find it difficult to defend their goal after taking the lead. PSG is also not determined this season in UCL, because I don't see any motivation in them.
PSG and Manchester City must both improve their way of playing in the Champions League this season especially when they will meet in the next match in the Champions League this season. I also can't say about the prediction of who will win their match because both of them have not been so good in the Champions League this season so it's hard to say about the prediction of who will win between them.
Manchester City just had another draw against their opponents who they could actually beat, and they were actually already 2 goals ahead, but they couldn't maintain it.
Manchester City's defense has been having problems lately, yes they are quite easy to penetrate, so this is also something that Paris Saint Germain can take advantage of. The match is getting closer, and their performance is inconsistent.
On the other hand, Paris Saint Germain is also having problems in the Champions League this season, they even have to get out of the zone that could take them to the play-off round.
