Leeds United are reportedly keen on signing Kemar Roofe from Oxford United.
Duberry also played for Oxford during his career, and he has kept a keen eye on his former club’s progress since retiring.
As a result, Duberry has seen Roofe in action on numerous occasions and he has backed the 23-year-old striker to be a good signing for Leeds.
"You know about his goals, his pace and his creativity but he’s also got massive amounts of confidence," Duberry said.
"That would give him an edge in the Championship because he’d go to that level thinking he could make it and cope there.
"He’s got the talent and his performance level this season says that he’s one of the best players in the lower leagues."
Roofe is understood to be high up on Garry Monk’s transfer wishlist, after he took charge at Leeds.
Monk is yet to make a signing, but Leeds are believed to be closing in on bringing Roofe to Elland Road.
Roofe hit 26 goals for Oxford last season, and won the League Two Player of the Year award.
Roofe is expected to cost around £2 million, and Leeds are believed to be willing to pay the fee to sign the attacker.
Leeds have also been linked with Sunderland midfielder Sebastian Larsson, since Monk was announced as their manager.
