Brazil left-back Marcelo says his "one final mission" is to "bring the Brazilian flag back to the highest level" by winning the 2018 World Cup.
Marcelo fell out of the Brazil national set-up after clashing with former coach Dunga last year, and was not involved as the team failed to make it out of their group at the Copa America Centenario.
However, he has captained the team under new boss Tite as they have easily ensured their place at next summer's tournament, even as historic rivals Argentina are struggling to make it through qualifying.
In a piece under his own byline for the Players Tribune, the 29-year-old recalled over a decade of tough times with the Selecao, but said the personal touch Tite had brought to the job was going to bring its reward in Russia.
