Dereck Chisora’s sparring partner believes the EBU Heavyweight title-holder could knock out Tyson Fury early in their WBO World Heavyweight title eliminator clash next month.

Former world heavyweight title challenger Mariusz Wach will spar with Chisora for the next four weeks as he helps him prepare for his showdown with Manchester-born Fury.

The 6ft 7½in Polish giant said: “Fury is a good boxer with a powerful punch, but he’s going to need something big to keep Chisora off him.”

Wach and Chisora started training together this week and have sparred just once so far but the Krakow-born boxer has felt the Finchley fighter’s power already.

“Chisora is a high pressure fighter, constantly moving forward looking for openings to land his big punches and when they land they hurt,” he continued.

“If Chisora can start fast, go under Fury’s punches and connect with his big punches, then I can’t see Fury standing up for long and he’ll go down.”

Chisora goes toe-to-toe with Fury on Saturday, July 26 at the Phone4U Arena in Manchester.
