Neville: Real Madrid ace Ronaldo is Man Utd legend
"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.
"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)."
