Shannon Briggs believes David Haye is 'terrified' and is still pursuing a fight with the British heavyweight.
The American arrived in London earlier this week to issue a challenge to David Haye, Tyson Fury and Anthony Joshua.
But Briggs failed to find Haye when he paid a visit to his Vauxhall gym and has suggested the Londoner is reluctant to face him.
Haye is hoping to lure the newly-crowned WBA champion Lucas Browne to Britain with a lucrative offer, although Briggs remains determined to secure a future showdown with the 'Hayemaker'.
He told Sky Sports: "I can't find him nowhere, been everywhere, you name it. Brighton, Knightsbridge - all over the place - Sheffield, Essex, Manchester - man you name it. Castles, I'm looking for him everywhere.
"I think he's afraid, terrified. I came here on a one-way ticket and I'm not leaving empty-handed."
The former WBO champion tried to hunt down a fight with Wladimir Klitschko in the past and insists the Ukrainian was not fully focused on Fury when he suffered a points defeat last November.
A rematch will be staged later this year and Briggs is expecting a similar outcome, unless Klitschko is willing to take more risks against the 6ft 9in Fury.
I feel Tyson Fury should call me and say 'thank you champ, I appreciate you champ'.
"Those two years when I pursued him and haunted him, chased him, it definitely took a toll on him," said Briggs. "He was distracted in some way. I feel Tyson Fury should call me and say 'thank you champ, I appreciate you champ.'
"If Wladimir isn't willing to put it on the line, it will be the same fight. He has got to be able to put it on the line. This is a guy who is close to seven foot tall and he's going to have to get inside and work him.
"I believe the size was the issue for him. I also believe he wasn't 100 per cent focused. He was living off his hype and was the champion for so many years. It was great timing and I knew that, because [Klitschko] had just had a kid. I knew it was perfect timing."
Anthony Joshua will attempt to win a world title in just his 16th fight when he challenges IBF champion Charles Martin at The O2 on April 9, live on Sky Sports Box Office.
Briggs shared the ring with former British great Lennox Lewis, suffering a stoppage defeat, and insists Joshua must battle 'all contenders' if he wants to follow in similar footsteps.
"I think that's a lot to ask considering the fact that Lennox had a very extensive amateur career," said Briggs. "He sparred Mike Tyson as a youngster. He had a lot of experience.
"I don't know Anthony's background, his experience, but that's a tough act to follow, but at the same time I think he'll do great.
"If he wants to be the next guy that Great Britain looks at as the great champion, he's going to have to take on all contenders, including myself. He's going to have to step up to the plate."
