Nikolay Valuev, who, at 7 feet tall, absolutely towers over his opponents before pummelling them to oblivion. Nikolay also happens to be the heaviest and tallest heavyweight boxing champion in history.
His British challenger has a mountain to climb, but in fact the Russian giant is a sensitive soul who wooed his wife with love poems and likes a bit of Miss Marple. His wife is tiny [5ft 2in] and they have two small children.
