WBO, WBA, IBF, IBO heavyweight champion Anthony Joshua would really like to see his close friend, Tony Bellew, pull off a shocking win over Oleksandr Usyk.
Bellew will challenge Usyk for the WBO, WBA, IBF, WBC cruiserweight titles on November 10 at the Manchester Arena.
Bellew is a massive underdog in the bout, with Usyk regarded as one of the best pound-for-pound fighters in the sport.
But Bellew has upset the odds several times since moving up from the light heavyweight division.
He captured the WBC title at cruiserweight and then vacated the belt to move up to heavyweight to secure back to back knockout wins over David Haye.
One thing Bellew has is power, and Joshua says the Liverpool fighter can change that entire fight with one shot.
"From a supporter's perspective it's always going to be entertaining because I really like rooting for Bellew," Joshua told Sky Sports.
"I really want him to win, so my passion is with him, regardless. Then, from an entertaining point of view, Usyk is like a perfect boxer, so I hope Bellew is working on his counter-punches as well, because that's the way to knock him out - let him tippy-tap and then explode. As we've seen Bellew can counter-punch and he's got a dirty left hook, and if he can land that I think he'll do well."
"If I am honest, Usyk is the favourite, straight-talking, because he's unbeaten and he's done it at cruiserweight and he's undisputed. But, the thing with boxing, from like middleweight up, it takes one punch. One punch can change the course of a fight and, as I was saying, Bellew's got that in the locker. We all know he's got that as well, so that's what makes it so interesting."
