Cristiano Ronaldo, Xavi and Lionel Messi were the trio shortlisted for the 2011 Ballon d'Or. Zlatan Ibrahimovic was not. But if you think Zlatan needs your silly awards (or any kind of outside recognition whatsoever) to think he's the greatest, you are sadly mistaken.
Said Ibra (via Soccernet):
"In my head I am the strongest of all. I certainly don't need the Ballon d'Or to prove that I am number one."
In fact, he doesn't even need to play football to prove that he's number one. Zlatan could comment on YouTube videos all day and he would still think he was the best and strongest footballer in the world.
Other things that are true in Ibra's head: kicking people is a reasonable way to show affection, putting your hair in a ponytail will give you x-ray vision and Pep Guardiola smells like a pile a "Pep Guardiola," which is an acceptable term for vomit that's been eaten by a dog and then vomited back up.
