A soft mattress may have been the reason Marcelo only managed 10 minutes of Brazil's final group game.
"We don't have an update on Marcelo's injury, I just know he has a problem with his back, he said his back was locked", revealed Brazil coach Tite. "The injury may be related to the hotel mattress".
"We all know who Neymar is but it isn't up to me, or my team, to judge him but the referees and Federation Internationale de Football Association".

Mexico face Brazil in a round-of-16 clash in Samara on Monday, and Guardado issued his appeal amid criticism of Neymar for going to ground easily during the tournament.
