He simply needs games in order to learn the position and become more comfortable at it which will come from confidence.
We signed him as a right back, he was used as a right back early in his career, he helped get Blackpool promoted as a right back.
Then spent the next 2 years as a right mid cause
Moyes didn't buy a proper right mid.
He has potential, at the moment sure he's rough round the edges but he's young and relatively inexperienced at rb so simply needs to be given time and games to improve.
If he isn't up it after that sure, replace him if we can. But for now he should be doing as we did yesterday, starting against teams below us in the league.
