If Luis Enrique had a striker like Mbappe in his squad, PSG's attack performance would have been more dynamic.
One of the problems PSG had with stars like Mbappe and Neymar is that they felt somewhat bigger than the manager and they put their egos ahead of the team. That said, when you watch PSG play now, what you see is a team and not individual egos, and it turns out it was a good decision that Mbappe, Neymar and Messi left and the hierarchy at the club changed their transfer policy to homegrown players, they are doing better now and they will achieve more success going forward.
I think that squad when Messi Neymar and Mbappe played was too many superstars at once. They didnt run and just couldnt pick up the tempo and that was the main problem of that team. Since every superstar left they play like a team and really look good like they can win the title and they have a big chance at that
