Zhilei Zhang has been waiting three weeks for Derek Chisora to sign his side of the deal for a fight at the back end of the year.‘Del Boy’ is set to co-headline a stacked bill on December 13 in Manchester, topped by Moses Itauma.Zhang has agreed to fight Chisora, but has heard nothing backMark Robinson/MatchroomIt will mark Chisora’s 50th and final professional fight.Zhang was offered to be Chisora’s dance partner and agreed without hesitation.However, Zhang’s advisor, Terry Lane, has informed BoxingScene that Chisora is yet to put pen to paper.“We’ve been very quiet about it because our team and Zhang himself we’re just not ones to rush to social media,” said Lane.“But we were presented with the fight [over three weeks ago], and we accepted [in] a couple of days. “So it’s been well over three weeks since the fight has been accepted on our end, in principle…“Queensberry wants to make the fight. DAZN [the broadcaster] really like the fight.“It was a twin bill with Moses Itauma as kind of a co-main event situation on a pay-per-view. “So we said yes, basically pretty quickly, and it just got to a point where we kind of felt like we needed to speak up in recent days.”What will Zhilei Zhang do if he doesn’t fight Derek Chisora?Growing frustrated by the situation, Zhang called out Chisora on social media last week.View Tweet: https://twitter.com/hashtag/boxing?src=hash&ref_src=twsrc%5EtfwRather than responding to the 6ft 6in giant, Chisora took to X, formerly Twitter, to challenge Deontay Wilder, Dillian Whyte and Jarrell Miller instead.If Zhang can’t land a fight with Chisora, then Lane insists his client will move on to secure a homecoming bout sometime in January.Zhang hasn’t fought in China since September 2018, when he stopped Don Haynesworth at the Changsha Social Work College.His last 10 fights have been abroad, either in the United Kingdom, the United States or Saudi Arabia.His profile has elevated considerably in the last seven years, so a big fight in China would undoubtedly be a massive commercial success.There have been numerous discussions over the years about Zhang headlining Beijing’s 80,000-seat Bird’s Nest Stadium.Perhaps now is the time to put those plans into motion.
