The defender came up against some of the world’s best during his time at Old Trafford, with the likes of Fernando Torres, Sergio Aguero, Luis Suarez and several others all opponents in the Premier League.
It is not the quick, pacey or skilful strikers that made Ferdinand found the toughest though; it was the big and physical forwards that gave him the hardest time.
And when asked who was his toughest, Ferdinand says former Bolton Wanderers forward Kevin Davies, and players of his type, were the worst.
“In the Premier League, I'd say people like Kevin Davies,” he told the Daily Mail.
“I was tall and lean, but physically, if it came down to a wrestling match and one of those guys pinned me, they had the advantage. So I had to work out ways around it, how to get to the ball first.”
“If you're playing against someone quicker or more skillful, you're just thinking about where to be on the pitch.”
Ferdinand’s pick is certainly an interesting one; especially given how he has enthused about Manchester City star Aguero in the past.
There are likely a number of former Premier League defenders who name Davies up there among their toughest as well though, given the physical displays he regularly put in as the focal point of Bolton’s attack under Sam Allardyce.
Whether the more physical centre backs would pick him among the toughest though is another question, with United partner Nemanja Vidic sure to pick the likes of Torres among his toughest given how he struggled against the Spaniard.
