Retired boxer Ricky Hatton believes Amir Kahn can fulfil his potential and become the best pound-for-pound boxer in the world.
Hatton, who suffered just two defeats in his boxing career, likened Kahn's fighting style and ethos to his own.
He said: "I think Amir is very similar to me. He is never in a bad fight and goes for the knockout."
Regarding Kahn's possible ascent to the top of the boxing pile, Hatton said: "I really do think Amir can be the best pound-for-pound fighter.
"When you look at Floyd Mayweather and Manny Pacquiao, they are not going to be around for much longer.
"So he is in there with a shout if he keeps improving the way he is improving right now."
Kahn recently defended his WBA light-welterwieght belt in a points victory over Marcos Maidana in Las Vegas.
The 24 year-old Bolton fighter is due to face Ireland's European champion Paul McCloskey at the MEN Arena in Manchester on April 16. Hatton is jointly promoting that fight.
Kahn recently parted ways with fitness coach Alex Ariza but believes that his trainer Freddie Roach has everything in order.
Roach's stable has produced current boxing legend Manny Pacquiao, who was one of two men to defeat Kahn's admirer Ricky Hatton before 'the Hitman' retired.
The other boxer to stop Hatton was Pacquiao's nemesis Floyd Mayweather Junior.
