The idea of Dier getting turned by a pacey winger is the stuff of nightmares, with out system we need a right back who can get up and down the line quickly, which sadly Dier does not possesI know it's unpopular but he can be coached to play RB.
I'll be delighted if he does, but I think it's unlikely.You'll be sorry when he has a blinder in the season coming up boys.
I definitely think there's merit until waiting until next season to see his true worth, he's probably the player who's suffered the most this season what with the the World Cup and the long term injury he had this season, I think the break will do him good.
Transfer him out he is a squad player at best in my opinion
