Unbeaten cruiserweight contender Lawrence Okolie is eager to make a big statement on Saturday night, when he faces former world champion Krzysztof Glowacki for the vacant WBO cruiserweight title.
A stated in recent days, Okolie wants to capture as many world titles as possible in the cruiserweight division before making the move to the heavyweight division.
At the moment Okolie can make the cruiserweight division with few issues, but it's not getting any easier as his career plays out.
He expects to be more dangerous once heading up to boxing's biggest weight class.
"For me, it's how comfortably I can make the weight. I don't enjoy it," Okolie told Sky Sports News.
"It's not hard, it's just I enjoy eating, full stop, so I have to be a little bit cautious. I have to go for long runs. I think I'll be a lot more explosive as a heavyweight.
"I owe it to myself to win this fight and have some unification matches, so I can say I've cemented my legacy on Saturday by being British, Commonwealth, European and world champion, however, for me it's not enough to have a cabinet full of those belts. I want WBO and IBF and WBC and WBA, so we'll see how many I can grab while I can still make the weight, and then we'll move up."
Okolie, who is managed to unified heavyweight champion Anthony Joshua, is willing to fight any boxer in the weight class.
"Really, it doesn't matter to me," he said. "Anyone that [promoter] Eddie (Hearn) can guarantee, I'll take. If it's Briedis next, I'll take it, Goulamirian, I'll take it. If it was Makubu. Any one of them, genuinely, I'll go for," Okolie said.
