Harewood signed from Nottingham Forest in 2003

West Ham striker Marlon Harewood has signed a new, improved contract.

Harewood signed a five-year deal last September but the new package - which still expires in 2010 - comes after he was the club's top scorer last season.

"I am enjoying playing football for West Ham and this is where I want to stay," said the 27-year-old, whose goal tally in the 2005-2006 campaign was 16.

Goalkeeper Jimmy Walker has also agreed a one-year contract extension, which goes through to the summer of 2008.

Harewood cost West Ham £500,000 when he signed from Nottingham Forest in November 2003.

He was linked with Tottenham and Newcastle over the summer but pledged to stay and battle for a place among West Ham's congested forward ranks.

Walker is effectively third-choice keeper behind Roy Carroll and Robert Green but is determined to fight his way into contention for a place in the starting XI.

"I appreciate it will be difficult in terms of first-team places, with two other top quality keepers here, but I will just keep doing my best," he said.
