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.
Even your statement is strong enough but we still need some more things which can bring better results for the teams like as few have few suggestions in above posts we need better midfield and defence as well here in PSG they recruited the best strikers in world, but their midfield is not good as they need to be which is surely problem with as things going we can expect good changes with new coach is also under radar, but nothing is perfect who is coming with Carlos Ancelotti is at Real Madrid and his contract is going to end June 2024 with Brazil and few others are strong candidates for hiring his services but if PSG able to take him then surely we can expect better results because he can bring good winning unit and better things for this team in long run.
