Promoter Eddie Hearn is targeting a blockbuster showdown for his boxer Kell Brook, with domestic rival Amir Khan, which brook insists can attract 50,000 people at an outdoor venue in England.
Brook continued his ascent to elite level this weekend as he wowed 10,000 fans at the Motorpoint Arena in his native Sheffield by outclassing British welterweight rival Matthew Hatton.
The unbeaten 25-year-old, who has been on the cusp of a world title challenge for some time, proved his box office appeal and big-fight temperament with a superb performance of poise and power en route to a wide unanimous decision victory.
Brook has long been linked with fellow Englishman Amir Khan and has called for a fight between the pair for years.
Now, however, he is making a name for himself in his own right and with a world title belt around his waist, hopes he can eventually lure former light-welterweight champion Khan into a scrap.
"It has to be a pay-per-view, outdoor fight, because he's got big revenue coming from HBO in America. So to bring it to seven, eight, nine o'clock at night, there has to be big money in the UK. With 40,000 fans and pay-per-view TV, that's a fight that can happen. Let me tell you, Kell would absolutely destroy Amir Khan. We'll fight him. We'll fight him next, 100% and make it happen outdoors with a crowd of 40,000 or 50,000," Hearn said.
"It's an easy fight to make money from," he said. "They would both get millions of pounds. It sounds easy. Or for us, we'll come back here in July and sell 10,000 tickets again (against someone else)."
