Yes, Paris Saint Germain will continue to dominate the league even though they are without Mbappe next season, because if we compare the composition of players they have with other clubs, then losing Mbappe should not cause them any problems. However, it is their dependence on Mbappe that may cause problems at the start of their season.
Their squad is quite even compared to other clubs, which makes them have no reason not to dominate the league anymore. Maybe some surprises could happen, but when we look at the level of consistency that the clubs in Ligue1 have, then they probably won't have as many problems as other clubs will do to them.
They have to learn from what they have experienced so far, they have to let go of their dependence on one player. because that will be a problem they will face one day, because after all no player stays at one club forever. Mbappe is a real example for them.
So far PSG has dominated ligue 1 very much and even many say that without mbappe PSG will also not have difficulty dominating the league, but I think still PSG will have difficulties at the beginning of this season, For now, Luis Enrique, of course, must be able to optimize their squad without Mbappe next season, besides that looking for other players who can indeed replace Mbappe position in the front line must of course be done immediately by PSG at this time because they need a fairly sharp striker.
PSG dependence on Mbappe has actually become a double-edged sword at this time, so far Mbappe has contributed
which is very significant to PSG, but on the other hand when Mbappe leaves like today it actually makes PSG look quite destroyed and no longer a scary strong team, that's why many of the big teams in Europe avoid them depending on one player, so that the team can remain stable even if their mainstay player leaves, I think for now it will be very difficult for PSG to be consistent in their game next season if they don't get another player who has the same influence and ambition as Mbappe.
