Brook [36-2, 25 KOs] lost his IBF world welterweight title after defeat to Errol Spence Jr. in May last year, but the British fighter believes that it will not be long until he is contesting titles at 154lbs.

"I want to be a two-weight world champion," Brook asserted after weighing in at 10st 13lbs 7oz for his comeback -- three ounces heavier than rival Rabchenko.

"I've never been satisfied winning one world title. Even when I was a teenager, I always wanted to move up the weights and win belts as I grow. I want to win a belt at super-welterweight at least, I need to get the win and then we can start targeting the champions at 154lbs.

"I just want to be in the biggest fights that everyone is talking about. I love being in fights that grab the attention of the fans, like the Gennady Golovkin and Errol Spence Jr fights did. Proper boxing fans knew that Spence Jr was the next big thing in the States, no one believed that I would fight GGG then come back down to defend against him.

"I love beating the odds and getting in there and performing. The feeling I get from going out there, hearing 'All of the Lights' and doing my thing in front of all of the fans, it's amazing for me. That's my drug and I can't wait to get back in there."

Brook recently admitted to ESPN that he thought about quitting boxing during a battle with depression that followed his defeat to Spence, but he is raring to go at his new weight, believing that he is perfectly suited to the super-welterweight division.

"I've had six months off so there was no way I was going to box at 147 anyway but I think that 154 is really going to suit me.

"I'm looking forward to having plenty in the tank at the weight and I'm excited to see how I perform at super-welterweight with the extra weight."
