PSG's job won't be easy in a tough group like Group F indeed. Newcastle, Dortmund and Milan are all challenging opponents for the current PSG. Because there isn't an impressive team play by PSG these days. They are expecting Mbappe to do most of the work. This can't help them be successful much in the Champions League.
This isn't the Ligue 1 in the end. PSG can find a way to maintain their title streak there but their job is very difficult in the Champions League. Mostly the team with the best team play win this title. We all saw what Manchester City did last season in the semi finals and finale even without Haaland's scoring or making an assist.
You are right but if you look at psg team very well you will understand that the team did not lack any position, psg have every position in their team and they have good stricker player and even the side wing player's that can dribble from the middle of the field and score gaols, although I know that psg did not have the spirit of winning champion league but the present squad can lead them to a better position this season in champion league because the team have good forward player's like mbappe, Dembele, and Asenso, this players are among the best players in the world and we all know how dangerous they are when they are playing in the field.
We can't use psg former performance to predict their present one because a game always change and we know that psg always try their best in champion league every season is just that they don't have the luck of winning the tittle, psg can defeat Dortmund, Newcastle and also I believe that they can defeat Ac Milan also, although I know they depend on mbappe performance but I still believe that psg performance will be great this season and if care is not taking they can make it to semi final stage.
