James Walker

Southend United After returning in January 2008, he was close to joining another League One side, Southend United, for £200,000.

The following month he was signed on loan by Southend, and scored on his debut against AFC Bournemouth.

At the start of Southend's 2008–09 season, Walker was used as a winger rather than a striker. On 13 December 2008, in the club's League One game against Huddersfield Town, Walker missed a penalty which would have put Southend on level terms, instead Southend slipped to a 1–0 defeat.
