To be honest, I don't think it would necassarily be a terrible idea to loan him to an EPL team, but like most cases, it's just about choosing the right one and whether the right one is actually taking an active interest in the loan. I feel Arsenal may(?) work and is the obvious first choice due to the midgets they have in that team anyway and the similar playing style. However it would perhaps be a better option to send him on loan to a team in a strong league, but out of his comfort zone, forcing him to learn new things and develop along a different path.
It's all hypothetical of course, only time will tell if whatever choices confront him and management will work out for the best. If it does not favour Barca, then who cares.
