Real Madrid captain Sergio Ramos is happy over his relationship with coach Zinedine Zidane.

Ramos has paid tribute to Zidane, who is such a popular figure due to doing the simple things well.

"We have a good friendship. I like being loyal to him and things with him are always simple and clear. It is a beautiful relationship and I have a friend for life with the coach," Ramos said.

"Diego Maradona once said, 'it is white or black but never grey' and that's what it is like with Zidane."
