The thing is, because he hasn't played much, he hasn't been hammered like he was when he was here, with summers spent playing for Brazil, or at Olympics then straight back into the grinder in the PL.
Maybe a break has done him good. Maybe the big city lights of that london have dazzled him all wrong. Maybe the machinations of levy's spurs are a Machiavellian mischief to far for him. Scored some goals, has a bit of character, seemed to get on with the support well. spurs might be keen to have a bit of wiggle room in the budget this summer.
