Manchester United legend Gary Neville says Cristiano Ronaldo deserves to be regarded as an Old Trafford great.

Neville said of the Real Madrid star in his column for the Mail on Sunday: "He is an absolute bully, as Maicon found out for Manchester City in the Bernabeu this season.

"He sniffs blood, he will find the weakness in the back four. If he's not getting the left-back in the first 15 minutes, he'll switch to the right-back.

"If he's not getting the right-back, he'll switch to the left centre-back.

"He'll find someone in your back four who is weak and doesn't like defending one on one and against pace and power.

"His skill, strength and speed were incredible.

"I had played with some great players in Roy Keane, Ryan Giggs, Paul Scholes, David Beckham, Eric Cantona and Mark Hughes.

"Because of their longevity at the club, they may be ranked above Ronaldo as United greats.

"But no one was a good as Ronaldo in that two-year period (2006-2008)."
