Both Ronaldo and Bale has been linked with moves to Manchester United, but Zidane insists the duo will stay in the Spanish capital.
“No, he [Ronaldo] is not for sale, it wouldn’t make sense,” Zidane told ShortList.
“Big players are what people want to read about, so that is why they are written about, but why would Real Madrid have any intention of selling the best player in the world?
“Cristiano Ronaldo has been the best player in the world for the past few years, and he knows he is the best.
“It doesn’t mean that he doesn’t work hard, or that he doesn’t want to improve and get better, but he has that confidence where he knows how good he is.
“I was not the most prolific goalscorer, but I knew how good I was. I knew that I could read the game and see things one or two seconds quicker than everybody else.”
“Of course clubs are going to want Gareth, he is one of the best in the world, but I am not sure how much clearer we can be,” Zidane continued.
“Gareth has made it clear, his agent has made it clear, we have made it clear, his future is at Real Madrid. We sign the best players in the world, we don’t sell them.”
