just keep playing him, more and more, and he will be a first team player before you know. once this guy is confident in the team , there is no telling how good he will get. a bit speculative but i think his situation is like pogba, made to be a star, pogba always plays like he is on cloud 9, thats through the belief he gets from starting for a big club. loaning him to bloody ipswich or wherever, is a surefire way to ruin his career, as is keeping him in the youth team too long. no ways around it, just play him whenever you can
