I know very well Dier, always felt he should be a CB since Sporting youth teams, for reasons I don’t know when he reached professional football somehow in Sporting first and later at Spurs they thought he was more suited to midfield, for me it was nonsense who prejudiced him, he is a nice bloke even if he left for peanuts.
I know working under Conte has been good for him,but don’t understand why drop Maguire in the first place and perhaps Southgate doesn’t have him in his plans for the future, but he is good enough to play alongside a starter for Argentina so don’t know why some here think Dier is a terrible player, if he was Conte would drop him off.
