There is something not quite right with Lionel Messi at this World Cup. I am the Argentina captain's biggest fan and he is the most wonderfully gifted player since Diego Maradona but, here in Brazil, I have been disappointed with what I have seen. Some people might say there is not much wrong with Messi at all, because Argentina are in the final and he has scored four goals to help get them there. But there is no question in my mind that the Barcelona forward has become quite static on the pitch in this tournament.
