Lewis: Hayes must match Valuev victory

Former world heavyweight champion Lennox Lewis believes David Haye will need a repeat of his performance against Nikolay Valuev if he is to see off Wladimir Klitschko in their eagerly-awaited unification bout in Hamburg next weekend.

Haye secured the WBA heavyweight crown with a brilliant mix of work-rate and accuracy against Valuev in a November 2009 fight that was billed as ’David and Goliath’.
