When you become the best athlete on the planet and an international sex symbol, it probably goes to your head a bit. Just to get to the level of professional footballer you've got to have an enormous amount of self-confidence and a bit of an ego...let alone the level he achieved.
So, when in the span of 3 or 4 years you go from the best footballer on the planet on his way to cementing his legacy as the best ever, to a player who is absolutely cooked and cannot even buy a goal in Europe's second-rate competition, it's probably not very easy to accept.
Dude doesn't have the humility to step back from the situation and admit that he's no longer the player he was. Instead everyone else is the problem.
We all have a right to be angry and obviously he can never wear the badge again. But it's also sad to see things come to this. Ronaldo the player, with his all-encompassing career, should be remembered better than this.
My god, if Messi leads Argentina to the World Cup I don't think Ronaldo's ego will be able to take it.
