The former Chelsea man faces tough competition for the World Cup, with Alex Sandro also setting his sights on a call-up for Russia
Atletico Madrid left-back Filipe Luis acknowledges that he is behind Marcelo in the Brazil pecking order, but hopes to seal his place for Russia 2018 as the Real Madrid star's understudy.
The former Chelsea defender will get his chance with the Selecao this week after Marcelo was ruled out through injury for the side's clash against Colombia on Tuesday.
With Alex Sandro impressing at Juventus and also receiving a call-up, however, he is by no means assured of making the cut for the World Cup in less than a year's time.
