Eddie Hearn, who worked for several years with heavyweight contender Derek Chisora, believes the boxer's upcoming trilogy fight with WBC champion Tyson Fury will be a hard sell.
Fury will face Chisora for the third time at The Tottenham Hotspur Stadium on December 3.
After his last fight, a decision win over Kubrat Pulev, Chisora became a free agent. He would later reach a deal to challenge Fury.
Back in 2011, Fury won a unanimous decision over Chisora. In the 2014 rematch, Fury battered and stopped Chisora.
"It's difficult because Derek is my mate, but I've obviously seen the response from the public and how they're disappointed with the fight," Hearn told Betfred's Lightweight Boxing Show.
"The fact that Tyson has beaten Derek twice already makes the fight a hard sell in that respect. Tyson Fury was always going to pick an easy fight for December 3rd ultimately and we thought that was going to be Manuel Charr, but as it was met with such disdain from social media, they went with Derek Chisora instead.
"If Tyson hadn't beaten Derek twice already, then two Brits going head-to-head is a pick we would have understood. The reason people are upset with this fight is because it's an unwanted trilogy. Del Boy always shows up and he's coming into the fight off the back of a victory against Kubrat Pulev. He will give everything in that fight."
At the same time, the event has already sold a lot of tickets and is likely going to be a sold out stadium.
"They've said they've sold 50,000 tickets already, so I believe the fight will sell out the stadium. Tyson Fury is a big name and people know who Derek Chisora is," Hearn said.
"It's a bit of a weird one, December 3rd without a roof but us Brits are a bit crazy and think it's funny, so we will turn up anyway. They'll need a strong undercard because I don't think it's going to smash pay-per-view records, but it could have been a lot worse. If Tyson would have fought Manuel Charr, then maybe nobody would have shown up."
Most believe Fury took the fight with Chisora to stay busy, with his eyes firmly set on a 2023 showdown with IBF, WBA, IBO, WBO champion Oleksandr Usyk.
