According to the manager of heavyweight contender Frank Sanchez, the unbeaten boxer would love to get the opportunity to secure a 2021 showdown with Oleksandr Usyk - if the WBO world title becomes vacant.

Usyk is the WBO's mandatory challenger to unified champion Anthony Joshua.

But there is a slight possibility that Joshua vacates the WBO title in order to have a high profile unification with WBC champion Tyson Fury.

At the moment Usyk and dangerous heavyweight Daniel Dubois are two highest ranked contenders under the WBO.

Sanchez is sitting in the number ten position.

"It's looking like some chance Usyk may pick up a WBO vacated title in 2021 (if Joshua vs Fury happens)," Sanchez's manager Mike Borao told Sky Sports.

"In that case, it would open a small window for Frank to fight for a title in 2021. Frank is world ranked in the WBO and a bout between two of the best recent amateur cruiserweights fighting for a heavyweight title would be intriguing."

Borai is having trouble getting opponents in the ring with Sanchez - and says unbeaten puncher Efe Ajagba wanted no part of the match.

At the time, both Sanchez and Ajagba were fighting under Premier Boxing Champions. Ajagba has since jumped ship to Top Rank.

"Few fighters are willing to step up against Frank," his manager Borao said.

"I tried to make a bout again Joseph Parker without success. Also, we tried very hard to make a fight against Efe Agjaba while Efe was with Premier Boxing Champions. That fight made sense for us, because frankly the gap in skill level between Frank and Efe is monstrous.

"Currently, Frank is training with [trainer] Eddy Reynoso and in camp with Saul 'Canelo' Alvarez and Ryan Garcia, preparing for an October-November bout. If we can't get another young prospect in with Frank, we will try for bouts against established fighters like Gerald Washington and Dominic Breazeale."
