FIREPOWER

DR IRONFIST boasts an incredible 40 KOs in his 43 wins — and 26 of those were inside the first three rounds.

However, he was recently taken 10 rounds by ex-world light-heavy and cruiserweight champ Tomasz Adamek, while ex-world champ Shannon Briggs, who has seen better days, took him the distance.

Also Albert Sosnowski and Cristobal Arreola, who are no world beaters, both took him 10 rounds and I think Chisora would have beaten those guys.

TACTICAL BRAIN

THE only boxer to hold a PhD, Klitschko is more likely to be found in the political ring planning campaigns as leader of the Ukrainian Democratic Alliance for Reform these days than inside the ropes.

Although the Klitschko brothers get slammed for their so-called 'robotic' and 'boring' style, the Dr uses it to great effect with ram-rod left jabs and big straight right-hands.

With Klitschko 6ft 8in, Del Boy is going to have to use his agility and speed to get underneath to unload.

CHIN

KLITSCHKO has got an iron chin and has never been floored. He's lost twice — first against Chris Byrd in 2000 when the fight was stopped because of a bad shoulder injury with Klitschko ahead on all score cards.

Then he suffered terrible cuts against Lennox Lewis in 2003 in a fight he was winning until the ref stopped it in the sixth.

Chisora has not been dropped as a pro either. Both his defeats were on points — to Tyson Fury and European champ Robert Helenius. But his whiskers will surely be tested in this.

HEART

CHISORA was unfit against Fury but he stuck in there and against Helenius he fought his heart out so he's not lacking in that department.

One thing is for sure, unlike David Haye against Vitali's brother Wladimir, Chisora is going to give it his all and go out on his shield if he has to.

Apart from Lewis, we have not seen anyone really put it to Klitschko yet so we don't know how he'll respond when he's in trouble. Chisora is not scared of Klitschko.

EXPERIENCE

WITH 45 fights and 15 world championship bouts, Klitschko has a clear advantage.

Chisora can't match that with his 17 total fights and four championship contests. But we've seen how Chisora handled fighting away from home against Helenius in front of a hostile crowd in Finland so we know he can perform under pressure.

He will relish fighting in Germany and will rise to the occasion.

STAMINA

IT'S a surprise Klitschko has gone the 12-round distance only three times.

Chisora has done it twice, but if he can set the same frenetic pace he set against Helenius, will the 40-year-old Klitschko be able to keep up?

Klitschko is always in 100 per cent nick but, at 28, Chisora is younger and fresher with plenty in the tank. If he can dictate the pace it could get interesting.

VERDICT

ON paper Klitschko is the winner but something is telling me Chisora.

Make no mistake, this is a huge test for Chisora and he's doing it the hard way by fighting in Klitschko's backyard.

For me I'm hoping that Klitschko won't be able to cope with Chisora's speed, movement and constant pressure using work rate.

If Chisora did it, it would rank alongside some of the greatest upsets in history. And he just might do it!
