Manchester United legend Sir Bobby Charlton believes Cristiano Ronaldo is capable of becoming an Old Trafford great.

"The number of goals he's scored this year, it's just been fantastic, phenomenal," said Charlton. "He's been sensational and we're not finished yet, there's a bit of the season to go. And I think he'll be breaking records for a long time.

"He's an all round footballer.

"He's a master craftsman."
