By Dave Lahr: It’s been ages since IBF/WBO heavyweight champion Wladimir Klitschko (55-3, 49 KO’s) fought someone with the right ingredients to knock him out and expose his weak chin. On April 30th, Wladimir’s time as a champion will likely come to an abrupt halt when he faces one of the best kept secrets in boxing in unbeaten 27-year-old Dereck Chisora (14-0, 9 KO’s).

This is a fight that Wladimir is going to need to be on constant guard in, because Chisora never stops coming. He doesn’t seem to mind that he’s going to take some shots every now and then. His whole focus will be to get inside, keep his hands busy while Wladimir’s trying to hold and land to the head.

Wladimir has been lucky in the past seven years that he hasn’t faced anyone that’s been good enough to fight him on the inside. It’s not that everyone that Wladimir has faced has been weak, but rather they just didn’t have a good enough inside game to take advantage of his inability to work inside.

Chisora is peaking as a fighter at the right moment and he’s going to be real trouble for Wladimir. In Chisora’s last fight against Sam Sexton, Chisora gave boxing fans a brief preview of how his bout with Klitshko will go on 4/30. Chisora was like a human dynamo the way that he kept coming forward and forcing Sexton to fight much harder than he wanted to.

When Sexton attempted to play the same tricks that Wladimir generally does by trying to hold onto Chisora on the inside, Chisora battered Sexton with his free hand until the referee had to stop the fight. It was over that quick. The Chisora-Klitshko fight could end much faster, because Wladimir is going to be looking to hold from round one and won’t stop holding for as long as the fight goes. It doesn’t matter if his trainer Emanuel Steward warns him against doing this; Wladimir will hold nonetheless because he’s too set in his ways and is beyond changing at this point.

For Wladimir to win this fight against Chisora, he would have to go back to the style he once had when he fought Ross Puritty in 1998. Back then, Wladimir was a nonstop puncher, capable of moving around the ring constantly to avoid his opponent’s shots. Wladimir can’t fight like that anymore unfortunately is more of a stationary fighter that needs to hold to slow down his opponents. That won’t work against Chisora. That actually is the worst possible style to use against a pressure fighter like Chisora, because he eats up fighters that hold on the inside by refusing to stop punching. The referee is going to have to peel Chisora off of Wladimir each time they get in close, because won’t stop punching for anything. I feel sorry for Wladimir.
