Regular readers will know I'm a fan of (Cristiano) Ronaldo, and an even bigger fan of the man who's assumed his mantle with quite astonishing success, Wayne Rooney. But Messi is on a higher plain than even that pair.
He needs to carry on the way he is at the moment and he probably feels he has to do well for a few more years, but I can't see him turning it down because he is so patriotic.
