Tyson Fury is ranked as the top five heavyweight of all time by the co-manager of Deontay Wilder.
Fury controversially drew with Wilder in 2018 but won a spectacular one-sided rematch last year.
But the rivals saved the best until the last minute with their epic trilogy clash in Las Vegas.
Fury scored three knockdowns, rising twice off the canvas in the fourth, to close the show with a knockout in round 11.
It cemented the Gypsy King as the best heavyweight in the world, but Wilder’s co-manager Shelley Finkel rated him as one of the greatest people of all time.
Asked where Fury ranks among the greats, Finkel told SunSport: “Maybe in the top five.
“You have to give Fury credit, he got up twice, even in the first fight, and he’s calm in the ring.
“He knows what he has to do and he does it very well. Time will tell where he puts him in history.”

Finkel, who began his boxing management career in 1980, has worked with some of the best stalwarts in history.
It featured Mike Tyson, Evander Holyfield and Wladimir Klitschko as well as Wilder.
The bronze bomber, who scored ten WBC title defenses from 2015-2020, weighed 17 stone the heaviest of his career for his trilogy with Fury.
For most of his championship reign, 35-year-old Wilder, scaled anywhere from 15-16 stone, was often shaping up but making up for it in brute force.
Past champions such as Tyson, 55, Holyfield, 58, and Muhammad Ali, who died in 2016, all cut a similar frame.
He knows what he has to do and he does it very well. Time will tell where he places it in history. ”

But Fury, 33, is an example of a modern-day heavyweight, piling on a 19-and-a-half stone on the pound against Wilder for the third time.
For this reason, Finkel warned that it would be difficult for any of the great giants of the past to overcome him, except for a certain three.
She said: “The little boys couldn’t beat him because of his size. Maybe, a George Foreman on Foreman’s Top.
“Ali was particularly gifted in the movement, but smaller than that would have been difficult.
“Mike Tyson might have been capable, even if he was only 215 or so.”
