That's what former boxer and Sky Sports pundit Johnny Nelson thinks of this Saturday's match between Brit Anthony Joshua and New Zealander Joseph Parker.
The fight, which is taking place in Cardiff, will be shown on Sky Box Office, and has the makings of an historic bout of boxing.
Not only does Anthony Joshua have fame beyond boxing, broadening the appeal of this clash beyond the usual audience of boxing fans. Three world heavyweight titles are on the line, with the winner to be crowned WBO, WBA and IBF champion.
It is also the first heavyweight unification match on UK soil.
"Even beyond the idea of a unification match, this has the potential to be one of the greatest fights ever," said Nelson.
"Joseph Parker is not getting the respect he deserves, people over here don't know him that well but in the Southern hemisphere he's like Anthony Joshua. This won't be a one-sided fight.
"He (Parker) hasn't had as many fights as Joshua and for him this is a defining fight but I think it will be one of Anthony Joshua's hardest so far.
"If Anthony Joshua wins it will be historic."
"This is one that pubs really should show"
Joshua's promoter Eddie Hearn agrees, telling Inapub:
"It feels like when Anthony Joshua fights it's like a national holiday now. Between that and the fact this is a unification match, this is one that pubs really should show.
"Even if you don't usually show much boxing you should seriously consider it for this one."
Boxing has become big business for pubs. An Ipsos MORI survey suggested Joshua's stunning victory against Wladimir Klitschko last year was seen by one million viewers in pubs, for example.
At the same time, a MatchPint report indicated that the average pub makes an extra £900 from a pay-per-view boxing event.
