Man Utd veteran Ferdinand: Beating Roma 7-1 my best moment
Despite playing at World Cups and in the 2008 Champions League final, that 2007 night at Old Trafford is the match defender Ferdinand looks back on most fondly.
The 34-year-old said: "I remember Alex Ferguson saying after the game that you get that kind of result once in a lifetime.
"That was the moment when everything clicked and every single one of our players deserved eight or nine marks out of 10.
"We'd have beaten any team in the world in that match."
