The Spanish press seem to think that Barcelona have gone as far as they are willing to. It's the third summer when he's needed reassurances, they haven't got anything new to say. Barca have pointed out that he was injured for 10 games and that in an injury free season he would have played more. So an old promise confirmed rather than anything new.
All of the press are saying the same thing - it's up to Thiago now, and he's a very quiet lad off the field so probably very few people around him know anything more, and they aren't talking. They're speculating that blabbermouth Dave may be right, but no one that I've read is claiming anything even vaguely in the know, apart from what we know!
Thiago's own description. "I understand patience, I've been patient. But now I've played at every level for Spain except to the top one. To play for them I need to prove my value by playing football for my club."
