The former Tottenham Hotspur and Aston Villa striker believes that Cantwell would make the current Leeds team better.
According to Football Insider, Leeds are interested in signing the 22-year-old midfielder from Championship club Norwich this summer.
It has been reported that the West Yorkshire club have made a bid of £15 million for the 22-year-old Englishman.
Bent told Football Insider: “I really like Cantwell and it surprises me nobody else has been in for him.
“As a midfielder I really like him, he’s good on the ball, he can create chances, score goals and has got great celebrations. I want to see him back in the Premier League because I think he deserves to be in the Premier League.”
