Dereck Chisora is hoping that one rematch will lead to another.

On May 27th at the Hartwall Arena in Helsinki, Chisora will finally get the opportunity to avenge a controversial decision loss to Robert Helenius. Their first meeting took place in 2011, with Helenius walking away with a close points win that many felt should have gone to Chisora.

Back then, the two fighters were handled under different promoters. Now both of them are fighting under the promotional banner of Sauerland Event.

Chisora and Helenius finally came face to face at a recent press conference to officially announce their fight. The WBC 'silver' heavyweight title will be at stake.

This time around, Chisora will not be looking for a simple win. He wants to avoid the possibility of a controversial decision loss and intends to go for a knockout from the opening bell.

"I haven't seen the guy for almost six years. It was good, there was nothing much happening," Chisora said to Sky Sports. "We're not on game time yet, we're just training. I always say to myself, when I get on the plane, when I go to fight in another country - it's war time, it's game time. He looked friendly. Last time he was on edge, but this time he was okay."

"We're going in there to have a knockout. We are not trying to get points to be honest with you, because last time we left it to points, we got robbed. This time we're going to try and get a knockout."

Beyond Helenius, Chisora wants to avenge another defeat - a close decision loss to Dillian Whyte - which took place last December. It was one of the best action fights in the heavyweight division in many years.

"The fight will happen," Chisora said. "If he wins his next fight and then the terms are right for me and him, we'll do the fight."

"Everybody always say it has to be a world title eliminator, it has to be this or that. To be honest with you, if it's a great fight, it doesn't have to be for any title as along as everybody is getting paid."
