He said in an interview about 10 days ago, that his weekly preparation was different in 2013, to 2012. He wants to get back to his "old" preparation next season. I'm also pretty sure he was carrying some sort injury,
possibly to the buttock area last season. Two weeks in a row I saw him head to the bench very late in the game, and he looked very ginger sitting down. All might mean nothing, or might mean a lot. I'll let you decide!
