Yesterday was the best he's looked since his Benfica days. I think there's a big confidence and motivational issue that, if it can be addressed (which looks it might just be happening), then he can become a very effective player at a high level, maybe not for us but who knows.
I suppose if you were him there's now more of a carrot to playing in the same league as the parent club, maybe it ads sense of worth to his position going forward; whereas before maybe he felt we were just looking to window dress him for foreign clubs, now at least we've given him the chance to adjust to the league he was signed to play in showcase his talents.
Look, I hope he keeps it up because if not saving us money it'll get him a move/opportunity to play at a high level than he was looking like playing at prior to January.
