PSG will always dominate the league one every season, because I don't see any club in the league that can stop them from wining the league title this season. Currently Dembele as go injured during the international break and he will spend like 6 weeks before coming back to the squad and he will miss there tough match in the Champions League against Barcelona, but am still get believe on PSG because they have many key players even without Dembele they will still win matches because is not the first time Dembele used to go injured and they are still wining matches. After the international break they will face Lens in the league match and I don't think they can lose the match because they have the opportunity to win because they are playing at home and he as be long psg lose against Lens at home let see how the game will be but I still don't have doubt about Paris is just the ucl that will be very tough for them because of the injuries players.
Yes they will keep dominating the league and for this season they are still the favourite to win the league, the information about the injury of Dembele came in yesterday in his international duties for his country France but without his presence in the team I think PSG won't find it difficult to win league games but in the Champions League match against Barcelona it's going to affect PSG if Dembele does not return from injury to play the game.
