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.
For Mbappe, the end of the season turned out to be difficult, he had some controversial issues regarding money with PSG (something about bonuses in the contract that had to be returned), this clearly affected his play, as a result, the last games at PSG were very weak and I see that nothing has changed at the Euro, perhaps he just needs time to rest before the new season, and now he will have such an opportunity. I don’t think that Ancelotti is very worried about this, he has many forwards who are ready to score, and if one of them has a temporary decline, it will not be a problem for the team.
