#1 Marcelo (Real Madrid)
The Brazilian international has been the best left-back in the world for a while now. The 29-year-old was one of Real Madrid's standout performers as they won La Liga and the Champions League last season.
He was previously criticized for his lack of defensive ability when he joined the capital side but he has worked hard to improve and evolve his game. He has featured 4 times in the FIFA FIFPro World 11 in 2012, 2015, 2016, and 2017
Instead of providing overlapping runs to give width to the attack, he drifts inwards and creates danger from there. He has the technical ability that can be associated with most number 10's.
He has scored 4 goals and provided 6 assists for Los Blancos this season and is instrumental for Madrid's campaign in the Champions League.
