Manchester United midfielder Casemiro says he and Bruno Fernandes have a rock solid relationship.
The pair have been seen this season regularly arguing in games.
But Casemiro, ahead of Saturday's FA Cup final, said: “I have a very good relationship with Bruno, we get on really well, and as you get to know him as a player, I can say this with complete confidence, he is one of the most important players at the club and everyone sees what a great player he is.
“We could spend all day talking about how good Bruno is because he is a fantastic player but to be honest and I say this to him, I expect a great deal from him because in my eyes, he's one of the most important players in the team.
“So, when he misses a chance, when one of his passes goes astray, we always want him to do everything perfectly but these are normal conversations.
“I've never had an argument with Bruno, the opposite in fact, I just always demand a lot from him, and he demands a lot from me too.
“Behind the scenes too, sometimes we'll say to each other, 'You could have scored, you could have done better there, because you've got the quality to do it'."
