The Real Madrid defender started his career with Fluminense in Rio de Janeiro. He moved to the Bernabéu in 2007 and has won La Liga three times, the Copa del Rey twice and the Spanish Supercup on two occasions.
Why has he been selected?
Although he was not chosen by Dunga for Brazil’s 2010 World Cup squad, Marcelo has a lot of experience at international level and is, undoubtedly, one of the best players in his position. He is also a player that Luiz Felipe Scolari knows and has shared success with, having won the Confederations Cup with Brazil in 2013.
How has he played this season?
It has been a better season than last, when Marcelo’s domestic appearances were limited by injury. The Champions League Final against rivals Atlético is another chance for him to impress a global audience before flying to Brazil.
What will his role be in Brazil?
The 26-year-old will be the Seleção’s first-choice left back and is expected to be a reliable member of the starting XI, demonstrating the increased maturity and discipline that he has displayed in recent years.
