I feel like PSG will get better, they had a huge off-season where Mbappe was almost gone, Messi left, Neymar left and that is their big three, not having them is a big deal. Now they are going to get used to their new squad and I bet that they are going to do very well too.
I know that it might look like we are talking about a situation where it is not a big deal as of right now, but I bet that it is going to be a big deal when the time comes. Obviously it may take a while and we may end up with a situation where they fail to get a win here and there, but even last year they barely won the title with those great players, so it may not be all that great this year too, but I bet that they will get the league at least.
I don't think with PSG have did very well performance last two matches in Ligue 1 failed for three points achievement, last match PSG got draw against Tolouse and they can't scoring goals trough open play match after Mbappe goal from penalty kick. Need time for PSG waking up after losing many important player last season, left by Lionel Messi, Neymar, Sergio Ramos and last rumor left with Marco Veratti make PSG have rebuilding with their new player and they need time for adapting in Ligue 1.
Ousmane Dembele appearance forty minutes last match can't give contribution well and PSG difficult scoring goals, have been two match PSG scored one goals and seems bad starts in Ligue 1 not only difficult for winning but also get the same difficult for scoring goals.
