Portugal coach Fernando Santos says he's available to Juventus striker Cristiano Ronaldo if he needs advice about his future.

Ronaldo's future at Juventus has become the subject of intense speculation in recent weeks.

“If he were to ask me for advice on his future, I would always be available," Santos said. “I could certainly give it to him.

“I know him very well, I have trained him since he was 18, I have a great relationship with him. We talk a lot, but the things we tell each other stay between us.

“Cristiano has won everything at club level, after the European Championship in 2016, he only has to win the World Cup."
