Last March, in one of the biggest surprises of the year, Tony Bellew moved up to the heavyweight division and pulled off a TKO victory over former two division world champion David Haye at the O2 Arena in London.

In the sixth round, Haye's right achilles ruptured and that made him a one-legged fighter, and also changed the entire fight. Bellew took over, dropping Haye twice in the contest. The second knockdown, in the eleventh round, prompted Haye's corner to throw in the towel.

A few months later, Haye announced that he was parting ways with trainer Shane McGuigan, and later hired Cuban coach Ismael Salas.

The rematch was finalized for December, but November 20th it was revealed that Haye suffered a bicep injury during training camp and the contest was pushed back to the new date of May 5th, also at the O2.

Former super middleweight champion Carl Froch knows more than enough about rematches.

After tasting defeat at the hands of Mikkel Kessler, he got revenge by winning a competitive decision in the second fight. And then after getting dropped and having some struggles in his first bout against George Groves, he set the record straight by knocking Groves out cold in the rematch - before a crowd of 80,000 at Wembley in London.

Froch believes the Haye vs. Bellew rematch is a lot closer than it was the first time around.

"Whether David Haye is as fast as he was, or strong as he could be at the age of 37, is one thing. But I do know he believes in himself and believes it is all back," Froch said to Sky Sports.

"He did say all that in the first fight, but he also just dismissed Bellew. He won't do that this time. He was wound-up but he had no respect for and totally disregarded him. It was a bit like me and George Groves. In the first one I just thought I was going to go in there hit him on the chin and iron him out. And I mean as soon as I hit him. But then, it was suddenly hard to hit him. I was trying too hard, trying to load up and all of a sudden I realised I hadn't taken the training that serious.

"David says he didn't do what I did, he trained properly and was not over-confident or arrogant. Maybe like me, he just thought he would get the job done with no fuss, then move on. Throw in the unusual endings to both, it is so similar to what I went through. Yes, I won the first one, but people were genuinely expecting me to lose that return. Will people think the same about Bellew? I still believe this is a genuine 50-50, even if I didn't last time. Haye now goes into this rematch knowing that Bellew can punch, can box and can take his shots. He took his punishment. Will anything change? Well we will see..."
