I thought we were only overtly harsh on Everton youngsters?
Went to Utd at the wrong time in his career when he needed to go somewhere where he could continue to develop as he was at Swansea, without the pressure that he inevitably received.
Club career has stalled but I've seen more than enough for Wales and Swansea to know he could be a very decent player. Maybe not elite, but very good still.
Wouldn't mind him coming in for a decent price (as @TheRam
said) or maybe a loan for the remainder of the season and see how he gets on.
