As previously reported, a deal was reached for 38-year-old Alexander Ustinov to faces 31-year-old Briton Dereck Chisora in a crossroads heavyweight battle on July 11 in Manchester, England.

Ustinov's promoter Vladimir Hryunov says the contracts have been signed. But, he reveals that Chisora is already causing trouble with his antics.

After signing a contract, Chisora told Hryunov that there is nothing more to prove in facing Ustinov - because he handled Ustinov in sparring. Ustinov was brought in as a sparring partner for Chisora, when Del Boy was preparing for his rematch with Tyson Fury last year.

"Chisora ​​came to the press conference for Chudinov-Buglioni, and for some reason he began to show videos of his sparring sessions with Ustinov. He focused on the moments when he inflicted accurate punches, and said that in the sparring he had a clear advantage and now he supposedly has nothing to prove. He did not even bother to edit the video, which also had moments when Ustinov, in turn, literally carried [the entire sparring session] by himself. I do not know what purpose he intended, because the contract has been signed for the fight," Hryunov said.

Hryunov also noted that Ustinov is very serious about the upcoming fight with Chisora.

"Alexander is now in Minsk and preparing for Chisora, - he said. - "Currently he's working with three foreign sparring partners, two from the US and one from Europe. One of the sparring partners is Sherman "Tank" Williams, whom we brought in to prepare him for the fight with Chisora. So Alexander's preparation is going very well. "
