Xavi is soon going to join the Museum. Sorry. Although he is more tired and drained than anything else. He can't handle 2 games a week and big games. Rest him, and he will play better, but he is not going to get better that is for sure. He will start declining as all players do and it is okay, how Barcelona deals with it is another story. Pirlo, Del Pierro, Totti, Gigga, Scholes, Zanetti (though he is insane), all get time managed and special treatment, it is time for Xavi to get special treatment. Because he isn't the problem, because he is a function of everything around him.
Thiago, is all raw and experience will continue to get the best of him for a while and this is natural. It is Busi who in my opinion who is the greatest issue (a long with Messi) because while he puts in a lot of effort, none of it is tactically correct. I mentioned the whole drop in as a CB before and that has been abandoned but maybe he is tired? Maybe he just had enough? When he looks over and sees two full backs bombarding forward he gets confused? He has been losing his cool a lot, and that was his biggest strength. I also think Xavi misses Iniesta, when Andres is too far away he just doesn't trust anyone else that easily.
To me the biggest miss is Adriano, he seemed to be an impact player who can keep the defensive line somewhat organized. But the fat man can't keep himself fit, which is fine by me because when he is fit, he is a pain in the ass.
Puyol is done. So is Alves.
What Barcelona needs is someone like Suarez because the man has an unshakable amount of confidence, he is not catalan and is a thorn in every defense's back. He is just a menace. And he is not Catalan. Like Alba who thinks he has earned all the rights to complain, shout and brag when he accomplished nothing with Barcelona (yet).

Messi either needs better wingers or needs to be thrown out to the right like before to get his ass in shape because as long as he scores and gives the coaches no reason to get more out of him, your team will suffer in big games. He can only do so much, yes even him, even if he doesn't see it.
