Man Utd legend Charlton admits Ferguson rocked by Real Madrid defeat
Charlton revealed the extent of the hurt that Fergie has felt after last week's Champions League defeat.
He said: "Going out has hurt him a lot. You have to work with him daily to see that. If there is an opportunity and you miss it...
"But the desire is still in him to win that trophy again and I don't see why he can't. We have a great football club and Sir Alex is the greatest manager there has ever been."
