Although the England captain conceded a penalty in Saturday's win over West Brom, his trip of Jerome Thomas turned out to be Ferdinand's first foul since March.
"His first foul for three months, and it was a penalty. He should be disappointed," smiled the United skipper.
"Seriously, that is a great run. He is so good at reading the game. He does not commit himself when he doesn't need to, which for a defender, is very important.
"He is such a good footballer and is playing really well just now."
