Pique's a prick.
Also wonder how much it has to do with the passing of the 'old guard' in Puyol and Xavi. I know Puyol's been out of the picture for a while but it's well reported that Xavi played a big role is regrouping the side last year and getting Enrique and Messi to play nice. By comparison, the likes of Pique, Alves and co behave like children.
Iniesta and Messi are the nominal leaders in the team but they aren't the ones to sort team dynamics out.
