Real Madrid star Cristiano Ronaldo can't split coach Jose Mourinho and his former Manchester United manager Sir Alex Ferguson.

Ronaldo sat on the fence when quizzed which of his big-time bosses was best.

He told The Sun: "It's not fair to say, it's like comparing a Ferrari with a Porsche.

"Both are very good, very experienced and both like to win - and I mean to win everything.

"That's why they have both been champions many, many times."
