David Haye says he will prove he is more than a 'mouthy little Englishman' against Nikolai Valuev.

The Londoner has vowed to back up his taunts when he takes on the seven-foot WBA heavyweight champion in Nuremberg on Saturday night.

Haye has upset the Russian and his camp with his pre-fight taunts and was at it again at the head-to-head press conference at the Maritim Hotel, claiming the champion has fought nothing but fighters past their best.

Valuev's camp responded by claiming they would "shut his dirty mouth up", but the Brit remained unbowed and says he will back up those words when it really matters.
