I kept Rafael at Man Utd, but after my first season I sold him for ?40M.
I feel that at Man Utd, you're obliged to go for English players, so ideally I wanted Nathaniel Clyne, but Southampton wanted way too much for him. Same goes for Kyle Walker and Callum Chambers was not progressing well so in the end I went with Gino Peruzzi.
Didn't get Carvajal as he wasn't doing that well in terms of average rating at Real Madrid.
