Northampton Town signed Leeds United striker Leon Constantine in July 2008. 6ft 2in Constantine was born in Hackney and played for Edgware Town before joining Millwall in September 2000. He had loan spells with Leyton Orient and Partick Thistle, before moving to Brentford on a free transfer in August 2002. In August 2003 joined Southend United, initially on non-contract terms, signing a permanent deal the following month. After scoring at a rate of one every other game for Southend, he moved to Peterborough United in May 2004. In October 2004, he joined Torquay United on loan and in December 2004 made the move permanent for a club record fee of £75,000. Leon moved to Port Vale in November 2005, initially on loan, where he became a regular goalscorer. In the 2006-2007 season he broke a record, becoming the only Port Vale player to score more than 17 goals before Christmas. He finished the 2006-2007 season with 26 goals in all competitions for Port Vale (and 38 in all in 18 months for the club) and after being linked to a number of League One clubs in the summer of 2007 he agreed a move to Leeds United on a 2 year contract. He scored on his first appearance for United, although a broken arm restricted his appearances for the Elland Road side.
