Fluminense captain Marcelo has joined teammate Felipe Melo in blasting Manchester City midfielder Jack Grealish.
Melo accused Grealish of chanting 'ole' during City's 4-0 Club World Cup final win.
"Everyone does what they want. I have my head, I'm not going to say if it's right or wrong," Marcelo told CazTV.
"In this competition, he has one and I have four cups. I know how difficult it is to win four titles like that. Everyone does what they want."
Marcelo, 35, won the CWC with Real Madrid in 2014, 2016, 2017 and 2018.
Pushed on City's celebrations, he added: "The game is played on the field. I don't speak bad or good about those who do this. That's football. You won, you really have to make fun."
