That regret has been forgotten by PSG and building a team that is more prepared to face the challenges coming next season and forgetting Mbappe. An experience that Enrique has to face to build a team which initially relied on star players and now he has to be pressured to be able to bring PSG to compete strongly in domestic leagues as well as in major competitions without relying on a star player like Mbappe.
It's a good time to build a team with young players or build new talents from recruiting young who can contribute in the long term and it's one of the best ways than spending large amounts of money on star players who can't last long and also give big losses. Nasser Al-Khelaifi seems to have already realised that building teams with star players won't give you a reputation in the longer term and building teams of reliable young players better guarantees a better future for the team.
There is nothing to regret because the interests of the team are greater than those of the individual. In fact, in my opinion, Mbappe is just a burden for anyone and it is difficult for any coach to determine his policies on the field. Now PSG must develop a clear road map to be able to compete domestically and in Europe. I think this transfer market must really be utilized well in order to get players who match the vision. I am sure that PSG remains a big club and they will always learn from their mistakes for the sake of a brighter future for the club.
We can say something like this: Mbappe was more prominent than PSG, and this must have made the other players uneasy in the team. I think that team awareness will be fully established in place of Mbappe, who left the team, and they will be more successful with the contributions of the new player. PSG no longer mattered to Mbappe. This is frankly sad. PSG now has a period without Mbappe and they will try to make the best of it.
Mbappe leaving is for the best interest of PSG. They have been winning the domestic league without and with Mbappe. When Mbappe and the other stars were they couldn't win the Champions league, which is one only trophy that they are lacking currently. Even if Mbappe had remained there for the next season they will still not win the Champions league and they will keep paying him the big wages he has been earning there. Now with Mbappe gone, their wage bill has been reduced and they are still going to win the French league 1. So for me PSG are the one that's going to benefit on the long run. They have opportunity now to bring players that are going to be loyal to the club. It was obvious that Mbappe wasn't loyal to the club any more.
