Speaking on his Rio Presents podcast, Ferdinand said: "You look at Antony, he's got a man-of-the-match performance and a goal and assist in two games. McTominay is playing like primetime Jude Bellingham at the moment. You've got Elanga, who's a flying winger.
"You've got all these players that are leaving the club that are looking like new, dynamic footballers because the shackles are off, and the cloud and the pressure of Old Trafford, the badge, all that that brings, is allowing them to go 'you know what, wow, what a difference that is'."
He added: "You're probably going to see the same from Rashford. It's about unlocking what has unlocked Old Trafford for these players to perform."
