‘The Special One’ dominated mandatory challenger Jo Jo Dan before retiring the Romanian-Canadian on his stool with four sessions completed and immediately switched his attention to luring Khan into the ring for a Wembley showdown on June 13.
“If you’re watching, come and get in here with me,” said Brook in his Sky Sports interview after the fight.
“I’ve come from the bottom and I’m at the top now. I know you’re delicate around the whiskers and I’ll take you out!”
Khan, 28, was ringside at the Palms Resort in Las Vegas at the Jhonny Gonzalez v Gary Russell Jr event when Brook made his declaration on US network Showtime and on Sky, although the ex-140lb king has shown little interest in taking the Yorkshireman up on his offer.
Promoter Eddie Hearn was hoping to emulate his success at Wembley Stadium in May 2014 when super middleweight champion Carl Froch stopped George Groves in a rematch – but may be forced to turn to the likes of former world champions Juan Manuel Marquez and Brandon Rios instead.
