16. Marcelo: Brazil
If someone asks a question of who is currently the best left back in the world, the first person that comes to anyone’s mind is Marcelo. He is a kind of a player who can be very effective while both attacking and defending. Marcelo’s ability to read the game, his passing skills, fantastic crosses and work rate are absolutely astonishing. He is a pure class player which is why he has one of the biggest roles to play for Brazil in the World Cup.
