Manchester United wants to give this player to Atletico Madrid and get Felix instead of him. I think since he already played in La Liga in the last season this cannot be a bad idea for him to play in the Atletico Madrid for the next season and stay away from Manchester United.
Will be a good idea and both parties will be satisfied by the player they get only problem will be that Felix is more valuable and to balance the swap deal i think Manchester United wiill have to pay Atletico Madrid extra money to settle the deal or they will have to offer an additional player.
Greenwood has played in the La Liga and didn’t disappoint that’s why he is on the radar of certain teams and if not for the saga between him and Manchester United i believe United would have want to keep him but it’s not going to be an option for the player because he feel betrayed by the team so the best deal United can get will be to make a swap deal with Atletico since both teams are looking to offload their player and the players are no more interested to play for their mother club.

Is it possible that Mbappe's arrival will enable Real Madrid to win the treble for the first time? What is clear is that they have to try to win the CDR trophy first.

It will be like a cheat having all these players in one team, without Mbappe Madrid are already dominating then imagine them adding more sauce to their already made squad, they plan to destroy the world. There is no doubt, they will easily dominate La Liga and any competition they play in provided they have a befitting coach. Ancelloti is good but my concern is when he leaves will they have a coach worthy to carry on his legacy?
