Ronaldo insists he had a ‘great relationship’ with Rooney at Manchester United.
He told News of the World: “Without a doubt, he can become the best player in the world. There are lots of players who are a delight to watch but how many make it look as easy as him?
“We had a great relationship and that is the sort of quality of player you want to be playing with. In training, he can volley a ball from 30 yards away and miss your head by one inch every time.
“It might not sound a big thing but that is how accurate he is all the time. He will be one of the world’s best for many years. The natural talent is there but he cares as well and will never give up.”
