Former two division world champion David Haye is in agreement with some of the recent statements from other fighters, that Tony Bellew must use his left hook to overcome the massive odds on Saturday night.
Bellew will attempt to pull off a major upset when he challenges Olympic gold medal winner Oleksandr Usyk for the WBC, WBO, WBA, IBF cruiserweight titles at the Manchester Arena.
The contest is being billed as the final career bout for Bellew, and for Usyk it's his final fight in the cruiserweight division before a move to the heavyweight ranks.
Nobody knows better about the punching power of Bellew.
Haye, who was a heavy favorite against Bellew in two bouts, suffered stoppage losses in both contests.
He was stopped the first time in eleven rounds, but his performance was affected by injury. But in their rematch earlier this year, Bellew dropped him three times and demolished him in five rounds.
Haye broke down the strategy that Bellew must apply to defeat Usyk.
"Having a long-range boxing match against someone who is so technically gifted could be the wrong strategy," said Haye to Sky Sports.
"Solid counter punches, get Usyk reaching, get Usyk coming towards him. I definitely feel Tony Bellew's counter punching skills are very underrated. I definitely found myself on the canvas a couple of times, because maybe I underestimated his speed of counter.
"He's [Usyk] always been very difficult and tricky to nail down. I definitely think he has the attributes to be a very awkward night for Tony, but having said all that, Tony's left hook is the equaliser. If Tony can land that left hook to the head, that left hook to the body, he can really get a foothold in this fight, and turn the tide."
