The Brazilian full back has been the preferred left back for the majority of the time since his move to Real Madrid in 2007. Marcelo is often described as a successor to Roberto Carlos and anyone worthy of that comparison deserves a place on this list. Marcelo is an excellent footballer all round and is more effective in attack than most left midfielders. Aside from that, the Brazilian is a better defender than many give him credit for. In all, Marcelo has made over 350 appearances for Real Madrid and has appeared 42 times for the Brazilian National Team.
