#4 Rafa Marquez
The former captain of the Mexican National football team became the second player from the Mexican soil to play for the Blaugrana. Even with the rise of Jonathan dos Santos, it is almost definite that none of his other countrymen will ever match his level of success with FC Barcelona.
A centre-back pretty much like Ronald Koeman, he is a very fine footballer, both with and without the ball. Like Ronald, Marquez’s ability to feed the Blaugrana with long-balls proved to be valuable when Barca’s midfielders were seriously marked out of the game.
Marquez is also an awesome free-kick taker, a fact that is easily overlooked since the Spanish club have never been short of free-kick specialists. He also holds the prestige of being the most-capped non-European Player in the history of the club.
