Less than three years after Assem Allam rescued Hull from falling into financial ruin, the goodwill toward the Egyptian businessman has turned into open hostility.
Allam was feted as a saviour after injecting about 40 million ($80 million) into the English soccer club when it was close to bankruptcy while playing in the second-tier League Championship in 2010. The team then secured a surprise return to the Premier League last season.
But Allam's desire to change the 109-year-old club's official name from Hull City AFC to Hull Tigers to attract investors and boost its marketing appeal abroad has provoked fury among fans and traditionalists.
The backlash only intensified this weekend when Allam responded to supporters' chants and banners of "City Till We Die" by telling a Sunday newspaper: "They can die as soon as they want, as long as they leave the club for the majority who just want to watch good football."
It made for a hostile atmosphere at KC Stadium on Sunday as Hull beat Liverpool for the first time in 17 attempts. It should have been a day to celebrate one of the best results in Hull's history, but instead all the talk was about the wrangle between the fans and the owner that could rumble on throughout the team's first season back in the top division.
"What we can't let it do is fester because it creates, at times, when things aren't going so well, an atmosphere that none of us want," Hull manager Steve Bruce said. "If we are Hull City Tigers or we are Hull City, whatever we are, we have got to stay together going forward because we need all the help we can get. We are a newly promoted team."
Bruce said he would talk to Allam.
"The chairman has put something like 70 million in," Bruce said. "Without him, there wouldn't be a club or a Hull City. It would be down the tubes, in my opinion. However, I have got to have a conversation with him because I don't think he quite understands what it means in terms of history and tradition."
Angry Hull fans sang "We're Hull City, we'll die when we want" during the Liverpool game as Allam watched on from the director's box with members of his family.
Bernard Noble, the spokesman for Hull City Official Supporters Club, said most fans want to see Allam stay as chairman but back down from his plans to press ahead with the name change.
But Allam's opinion is unlikely to waver. He recently said the word City is "redundant" and "irrelevant", and that he would prove to be a trailblazer for clubs changing their names "to something more interesting".
"City, town, county: these are meaningless," he said. "In marketing, the shorter the name the more powerful - think of Coca-Cola, Twitter, Apple. By next year, I will change the name to Hull Tigers."
