Drogba and his wandering mind

In the November Chelsea magazine Drogba gives and interview where he admits that his mind wanders while on the pitch, in all fairness to him he also says it happens to everyone.  Of course I have always wondered about his level of focus on the pitch and I have no doubt that his level of focus on the game when he is not in it is completely lacking.  I remember seeing him on the bench last season against Wigin, ipod in his ears and taking SWP hat from his head.  It is one thing to have fun but game day is his job he gets paid very well for and should act professional in my opinion.
