Man United's Scott McTominay transfer mistake laid bare as Erik ten Hag proved right

"For everyone, it's a good deal," Erik ten Hag proclaimed when addressing Manchester United selling Scott McTominay to Napoli on transfer deadline day last summer.

Seven months later, it is hard to argue it has turned out that way for everyone. No one in Naples has any complaints, with Antonio Conte's team sitting second in Serie A.

United were better with McTominay last season, as Ruben Amorim all but acknowledged when suggesting they are
