I think we'll see him make his first team debut next season under Pep, probably in a home game where the crowd etc can give him more protection from being kicked / abused by the opposition fans.
A class act, and Pep will give him a chance to show his skills in the first team. He might not make a huge impact next season but he's too good not to test at senior level, just such great awareness of space and such quick thinking and excellent technique.
