Casemiro to Manchester United has been completed and an official statement from Real Madrid has come out about it as well. If you told someone this deal could happen a week ago they'd mock you. Completely out of the blue. He is a much needed signing for Manchester United though, solidifying the midfield. I guess that's one way to make Ronaldo feel at home, bring in his old comrade.
What a signing, these are the signings Manchester United needs, matured minds not player like Rabiot who is a mummies boy, Manchester should not stop here they should continue because they needs more leaders in the team, and they should avoid signing Anthony because he is just like rashford and martial,so they should sign more experience players like casimero,these are the signing that can make Christiano Ronaldo stays just like you said, players like Gnabry or Sane can still come in.
