#2 Marcelo (Real Madrid)
For so long, Marcelo has been seen as the best left back in the world, and he has been. He is quite brilliant going forward, and has been a crucial part of Real Madrid’s considerable amount of success over the past few years. However, defensively, he isn’t one of the best. We have often seen him beaten by quality right-wingers, and he has been vulnerable at times, which has caused his side problems.
His talents going forward are unquestionable, and he showed this most notably in the 2013/14 Champions League Final, where he was probably Real’s best player. Going forward is where he does his best work, and that is probably why he suits Real Madrid. He wouldn’t do as well with a team constantly on the back foot and having to do a lot of defending, but in a side where he can almost play as a left winger, he looks like a bit of a world beater.
