If there is one footballer in the world who truly loves himself with 100% conviction, it has to be the preening, petulant, self loving show off that goes by the name of Ronaldo. He is always compared to Messi, which must drive him up the wall, as most pundits would consider Messi the better player, and would rather have him in their team. At least Ronaldo can console himself with a large mirror and loving gazes at himself (as he no doubt oils himself up), as he can at least beat Messi on the looks and body department.
A bit like me in the bottom photo after my 8 hour bath yesterday (a new record!).
