Not even zidane can manage such a huge ego in psg all star team.
Uniting the star players at a team never easy , instead to have the full power to get a maximall result ... they flopped on the field due each ego . That's the hard part , give pep guardiola the job ... he might handled it better , that's the problem in psg.
Pep Guardiola have extended his contract to 2025 but I will not doubt that he might walk away once Manchester City win EPL (done) and Champions League title (soon) this season. That way he will be able to join PSG and fix the team after getting ride from some annoying players and make the others more disciplined.
Zidane is also a good coach but I agree that the best fixture will be done by Guardiola for PSG. There is Klopp that might help PSG in my opinion but he comes after the previous two.
