Real Madrid coach Zinedine Zidane insists there's no problems between Cristiano Ronaldo and Sergio Ramos.

It's emerged this week there's tension between the pair after trading barbs through the press.

"It isn't something which is affecting us, we know that there is a lot of noise around this club, a lot can happen and a lot can be said," Zidane said to reporters.

"We are calm because we're only focused on what matters and that is playing football.

"They are very smart guys and they can say whatever they want.

"They have been together for many years and have won a lot together.

"One might say one thing and the other can say something else but that is for you, we are calm about it.

"There's no problem between them.

"All I can say is that I have two players who are a big part of the history of the club, both know what it means and who respect each other a lot."
