If they plan on playing him as a LW/RW then he has no future at Barca.
I just don't rate wingers that aren't good dribblers and quick enough, unless you're very versatile like Bernardo Silva.
Pimienta started to play him as a RW because he had no wingers in the team. I still think Collado's future is in midfield but versatility can't hurt his chances either. Setien also seems to like Collado and wouldn't surprise me if he'd be a part of the first team next year.
