He made $41.3 million last year, behind only Cristiano Ronaldo among active players.

Messi is so valuable to Barcelona that if he ever leaves, the club that buys him will have to pay a $340 million buy out.
Messi is one of the most private athletes in the world. There are only a few signs that he lives likes a guy who makes $50 million per year.
He has been spotted in a $240,000 Maserati GranTurismo MC Stradale.
He and a few extended family members live in a massive compound outside Barcelona. There's a top-notch Argentine asado set-up.

He's known to take the occasional private plane, like when he went to the Ballon d'Or gala in Zurich.
But other than that Messi is fiercely private. We know that he has a long-time girlfriend, Antonella Roccuzzo.
The two grew up in the same town in Argentina, and their families are friends.
They have a baby named Thiago.

Thiago is now a staple of Barcelona title celebrations.

Or when he got a private meeting with the pope, himself a huge soccer fan.
Or when he agreed to have a gold cast of his foot made and sold to support Japanese tsunami relief (it went for $5 million).
