It is Ligue 1, it is not the Premier League. PSG should under any and all circumstances still easily win the title. It is too one sided in that league. PSG has got billions backing the team. No other club comes close to that. And it is not like Mbappe leaves an empty space and they play with 10 men only. Someone will fill the gap and they have several top players sitting on the bench most of the time. There is a chance that several other players now thrive and become much better exactly because Mbappe is gone.
Yes, I also don't expect much from the other teams in Ligue 1, because their quality is still far behind if we compare it with Paris Saint Germain, that's what makes Paris Saint Germain have to be able to continue to dominate the league, if not then in my opinion it's a failure for them, because after all they are the best team from any point of view, there is no reason for them not to dominate. Missing Mbappe? In my opinion, that cannot be the reason because in terms of player composition they are still better than other teams.
I agree with you that this league is too one-sided, we can see significant differences between one team and another team. This is why it is not surprising that Ligue 1 is a boring league at the moment, because we cannot see very competitive competition, it is almost certain that Paris Saint Germain will be champions again next season with the strength they have, that is quite easy.
They are simply the richest team in Ligue 1, although considering how Chelsea has been doing lately, it might not be the only reason. In my opinion PSG also ran too many experiments with coaches. Luis Enrique did ok before he went to PSG, but to me it never felt as if he was a top coach. He won titles with prime Barcelona and the question is how much of it was his work and how much of the success was the natural result of the player's quality?
Xabi Alonso has truly proven that he can turn a no name team into a beast. He has proven it. PSG also had Pochettino and I don't like him at all. Never understood why PSG wanted him, but it might also have to do with the fact that the sheikh isn't actually a pro in football. It is one of his hobbies.
But we will see. My guess is that PSG will of course win Ligue 1, but they don't have a chance in the Champions League. Group stage yes, round of 16 and maybe quarterfinals, but then it will be game over.
