Speaking on TNT Sports, Ferdinand said: "Confidence has obviously left the building in terms of the striker department. They haven’t got great options in terms of numbers either.
"One of the things with Hojlund, watching him I get frustrated because he’s always trying to fight the defender and have contact.
"Sometimes release yourself from contact so when you have someone against you it’s easier to take the ball and get into areas where you’ll affect the game, in between the posts and in the box."
