Saka is a case of his own. Doesn't compare with TAA, certainly not with Eboue.
To me he definitely could be a winger - has everything a winger needs - and I agree what he wants is of importance.
But that doesn't mean he shouldn't be playing LB right now - in fact I'd like him to stay there, and improve (I think the defensive part certainly needs to be improved - doesn't yet have the awareness and LBs moves in the defensive sense).
I think the idea he could be one of the [size=small][font=Courier New]top[/font][/size] LBs (and a good, perhaps even very good winger, but not wc) is the right way to see it. Could be a massive asset there for us.
