Casemiro has defended struggling Real Madrid teammate Marcelo.
Marcelo's recent form has been less than exceptional, yet his Brazilian compatriot was quick to defend him.
"He's a great player and he's working very hard in training," he confirmed.
"Marcelo knows what he needs to improve, but equally he knows he is a phenomenon.
"Marcelo knows he's the best full-back in the world, but it's the coach's decision."
