Russian Nikolay Valuev weighs in at 22st 8lb while Britain's David Haye weighs 15st 8lb ahead of their WBA heavyweight title fight in Germany on Saturday
Londoner Haye is the heaviest of his 23-fight career, but is still exactly seven stone lighter than his opponent
While Valuev comes in lighter than expected as he looks to counter Haye's superior speed
Haye has lost once in 23 fights and is aiming to become Britain's first heavyweight world champion since Lennox Lewis retired in 2003
The 29-year-old Haye will be giving up almost a foot in height to the 7ft Valuev, and seven stone in weight. However, there have been greater height and weight disparities in heavyweight history
Haye has only fought twice at heavyweight and is the former undisputed cruiserweight champion but relinquished his titles to step up a division
Haye's trainer Adam Booth wears specially tall boots for sparring so his man can get used to aiming at a high target

Valuev (left) and Haye will meet at the Nuremberg Arena, Germany for the Russian's WBA heavyweight crown. Predictably, the fight has been dubbed David v Goliath
If Haye wants to be champion, he will have to become only the second person to beat the giant Russian
Valuev has been beaten just once in 52 professional fights, by Uzbek Ruslan Chagaev in 2007, and has 34 knockouts on his resume
Valuev last fought in December, claiming a controversial points victory over Evander Holyfield, while Haye has not fought since a fifth-round win over Monte Barrett last November
The freakish nature of the fight is sure to inject some much-needed hype into a depressed heavyweight division
