I have no issues with this guy.
Whether he eventually becomes good at crossing and becomes a good RWB then great.
If he is only good at defence and we have to use him sparingly - the guy is like no other in defence RB.
The guy may even be even good at CB one day. I just absolutely love the player.
He won't be deadwood because even if he is a substitute - he will be damn useful.
Attacking wise, we hardly have a set tactic, a set bunch of players, a set formation or potentially a set coaching method for him to perfect at the age of 21 - just relax with him.
I can honestly one day see this guy even as a damn sweeper in a back 3 if Shaw is playing as a CB nowadays.
