Lee Purdy is looking forward to proving himself a cut above his domestic rivals when he takes on Argentine Gumersindo Carrasco next month.
With Darren Barker forced out of a return to action in Matchroom's 'London Calling' bill on September 8, Purdy has stepped up as the headline act in a challenge for the IBF inter-continental welterweight title.
It is a belt that Kell Brook - the only man rated higher in the domestic rankings - recently relinquished as he closes in on a world title shot.
But for Purdy it is a huge step up after he lost the British title to Colin Lynes, although the Essex banger believes he was not himself that night in November last year.
"I might have under-estimated Colin, I felt I had done everything right but I really believe that I wasn't my best that night, and if I believed that was my best I would probably have called it a day," the 25-year-old told Sky Sports.
"But I've come back and had a couple of great wins and I believe this could catapult me right up there.
"Colin got his tactics right, I got my tactics wrong, my hands and feet weren't working together, my head wasn't working great. Fair play to him but I'll come again and I'll prove it on the eighth.
"Eddie put the fight to me and I said I'll take it without even thinking about it. I was knocking on the door of a British title shot again but this has come up and I believe I can beat him."
Carrasco comes to the UK with a stellar record of 16-0 with 13 wins by stoppage, but 'Lights Out' is not that impressed with what he has seen.
"You obviously look at his unbeaten record, he's a big puncher, unbeaten in 16 but people forget I carry a big dig myself," added Purdy.
"When I looked on Youtube at him I believe I've got everything to beat him. He's easy to hit, he's been down a few times, his defence is not great but it'll make for a great fight, we're both big punchers and obviously there'll be some big bombs thrown.
"He's fought a couple of opponents twice so maybe his record is not as good as it seems."
Purdy was due to defend his English title on September 8 but when the call came to fight for the IBF inter-continental belt he did not take long before agreeing.
"Eddie (Hearn) put the fight to me and I said I'll take it without even thinking about it," said Purdy (18-3).
"I'm absolutely buzzing. That's what boxing's all about, to be part of a big crowd and great line-up of fights and I'm grateful to be amongst it.
"You don't want to blink in this one because it could all be over early. It could go late, I'm prepared to go 12 hard rounds but if it ends early then so be it.
"I believe his style will suit mine, I'll be able to show things off I've not been able to before, he's going to come forward walking on to big shots. I think I'm going to look good in this fight and I believe I'll take him out.
"I'm always in an exciting fight and it's going to be an exciting fight for the fans to watch."
Promoter Hearn is expecting fireworks in a fight with two big punchers but believes Purdy can come away with the win.
"The IBF have got world ratings and inter-continental ratings, Lee Purdy is in the latter so we looked at the whole list and unfortunately the only one available was the number one," said the Matchroom boss.
"He fights exactly like Lee Purdy so it's going to be an electric fight. This is a total 50-50 war so Lee has actually got a chance to elevate himself into the top-10 of the world rankings, so you've got to take it.
"He was in training anyway so sometimes you've got take these opportunities. He lost the British title to Colin Lynes. He shouldn't really have lost that fight but he switched off and he's come back with two devastating performances and he's ready for the next step.
"When you take a plunge against a top-10 guy in the world, even if you lose you're still English champion, nothing really changes. It's just these are the kind of opportunities you've got to take with both hands and he's the kind of kid who can do it."
