By Sean McDaniel: A huge crowd of 30,000 fans are expected to stream into Upton Park on Saturday to witness the British heavyweight grudge match between David Haye (25-2, 23 KO’s) and Dereck Chisora (15-3, 9 KO’s) in a fight that promises to have fireworks from start to finish.

Haye knows he can’t have a disappoint performance like his last fight against IBF/WBO heavyweight champion Wladimir Klitschko last year in July, and he knows that this could be his last big fight if he loses.

By the same token, Chisora literally has his back against the wall and is in a must win situation after losing three out of his last four bouts. It’s not good enough to fight hard and still lose every time out against quality opposition; Chisora has to start winning some of these fights if he want’s to be anything more than just a journeyman/trial horse for the better fighters to compete against. Chisora will no doubt be laying it all on the line for this fight. Although he’ll get paid well for the bout, he won’t be able to rely on getting future big paydays unless he wins this fight. He can’t let Haye outbox him like Vitali Klitschko and Tyson Fury did to him recently. A knockout for Chisora would be a disaster. Losing will be bad enough, but getting stopped by Haye will be a crushing blow to Chisora’s once promising career.

Haye has pretty much all the advantages in this fight in terms of speed, power and mobility. Chisora has some advantages of his own in terms of heart, chin and work rate.
