I think judging what you say that I also agree and the only coach who can make them win the Champions League for me is Carlo Ancelotti.He has done well in every team he has managed,even in CSKA Moscow for a bit of time when he was training there and brought them on the Champions League several occasions.I think this coach can do wonders with a team like Paris and their superstar players,I am sure the experience he has would come in great help to Paris in trying to win the Champions League.For this to happen though Paris should pay him a huge amount of money so that he can accept the job and bring Paris to new levels in International competitions.
I believe that as long as we can keep this up, then it should not be a problem for PSG to eventually win UCL, they just need to continue to dominate like this. They have money, they are making even more money, and they can spend that money on buying players.
They are interested in Jude Bellingham now for example, not saying they will be able to convince him, but if they possibly could do that then it means one of the weakness' would be gone, get 2 more midfielders like that and suddenly we are talking about a team that could get an UCL title without ever facing anyone difficult for them. They need just 3 players, 3 players and they will be getting the UCL title without a worry at all, it is not about the manager, just get a midfield.
