PSG is an elite team, the quality of the squad they have always places them in the group of favorite teams to win the Champions League trophy. Their failure to win the Champions League was because the players did not have the mentality to win the competition. This was because the PSG players' mentality was not honed in the domestic league because every match they played there they were always able to win easily.
That is the reason why Ligue 1 is always dominated by PSG because their opponents are actually not that difficult, which makes the players not have a strong mentality because of the lack of resistance that is their experience. If PSG were in a domestic league like the EPL or in Laliga, they would probably have a strong mentality. to be able to win the UCL next season, but it's also true that unfortunately their mentality is not that strong because there is a lack of tough resistance in the domestic league which allows them to play more seriously.
But I also don't want to underestimate Ligue 1 and the fact is that currently PSG always dominates it and then wins it, so it wouldn't be strange especially without Mbappe. I'm sure PSG can still dominate there, except for the UCL next season, they must immediately recruit new players as Mbappe's replacement because it is important to compete again in the UCL in the new season, no one knows what PSG's strength will be without Mbappe but Enrique must be able to make many better changes to achieve PSG's desired goal, namely the UCL trophy.
