Former world champion Anthony Crolla believes he is capable of toppling the man that many regard as one of the best fighters in the world, Vasiliy Lomachenko.
Crolla is the WBA's mandatory challenger to Lomachenko, who also holds the WBO's version of the belt.
Lomachenko is scheduled for a unification clash with IBF world champion Richard Commey, but that contest could potentially get postponed after Commey suffered a hand injury during last Saturday's world title win against Isa Chaniev in Texas.
Lomachenko is scheduled to return on April 12 in Los Angeles.
A purse bid for the Lomachenko vs. Crolla fight takes place next Wednesday.
Crolla's promoter, Eddie Hearn of Matchroom, believes he can win the purse bid and take that mandatory fight to streaming service DAZN. Lomachenko is under contract with Top Rank, who have an exclusive deal with ESPN.
"I think a lot depends on news in the next day or two about Richard Commey," Crolla told Sky Sports.
"The unification has been agreed between Vasyl Lomachenko and Commey, but he hurt his knuckle in that fight. If that's the case, then I think that me and Vasyl Lomachenko will fight first. I'm just waiting on news now, like everyone else.
"Listen, there's no doubt he's a special fighter, but he's very unorthodox, so how do you study, how do you come up with a gameplan for a fighter like that? But like every other fighter, we'll watch as many fights as possible. We're lucky with Lomachenko, there's so much footage on him. He does a lot of things very well, but we think we can do well to unsettle him, and cause a huge upset."
Crolla feels confident in his ability to topple Lomachenko, pointing out that the two-time Olympic gold medal winner has already tasted defeat early on in his career when he faced Orlando Salido, who at the time was a big underdog in the bout and not expected to win.
"No man is unbeatable. It's been proven with Lomachenko. He lost early on in his career. Don't get me wrong, I think Salido knew what he was doing. He got away with a bit more than roughing him up, hit him low all night and missed the weight. Whether he tried to make the weight or not, I'm not sure," Crolla said.
"But no man is unbeatable, and that's proven there. Don't get me wrong, he's improved so much I believe since then as a professional. It was always a very big challenge to win a world title in your second fight, but he's that kind of fighter. But there are weaknesses there that we see and we're going to try and capitalise on."
