When Manchester United admitted defeat in their pursuit of Frenkie de Jong last summer, few would have anticipated that their fallback option would make such an astonishing impact.
But for all of the concerns that were raised about the size of the transfer fee and Casemiro having already turned 30, the Brazilian has been United's best signing in the past decade. Almost single-handedly, he has transformed United's midfield and played a crucial role in the club's resurrection under Erik ten Hag this season.
