Released by Liverpool as a youngster, 32-year-old Lambert completed a dream move back to Anfield recently as well as making the cut for Roy Hodgson's 23-man squad for Brazil.
Spells at Blackpool, Macclesfield, Rochdale and Bristol Rovers earned him a £1m switch to Southampton in August 2009.
While playing for Rochdale he scored the only goal of a League Two game against Northampton in March 2005 having started the game against another forward, Grant Holt, who also rose through the ranks to play in the Premier League.
Cobblers Mad wishes Rickie and England all the best for the World Cup.
