Kevin Mitchell says a partisan ExCeL Arena crowd will help sweep him to victory against John Murray.
The pair clash for the WBO Intercontinental lightweight title on July 9 in London.
Mitchell comes into the fight off the back of a loss to Michael Katsidis last May.
But he believes home support could prove crucial.
"I let my fans down against Katsidis, but I won't this time," said Mitchell.
"They are the best in the world and I know they will get behind me. It will be looking having someone in there with me taking the best of Murray's punches.
"People keep saying that I've got ring rust after the Katsidis fight, but I've had a nice long rest and I'm actually feeling really fresh.
"I'm going to be very, very sharp on July 9 and Murray is in big trouble."
But unbeaten Murray, the former European champion, said: "I'm sure that Kevin is going to get good support, but my fans will be there as well.
"I've fought in the States and down in London, and I've always got a good reception.
"The crowd might be chanting Kevin Mitchell's name at the start of the night, but they will be singing my praises by the end.
"When they see me in action they will realise that Britain has got another world class fighter.
"I'm so up for this fight. It's the one I have wanted for a very long time. Kevin's a great fighter, but he's not as good as me."
