The veteran striker secured a permanent deal at Selhurst Park after helping Palace secure promotion to the Premier League in May.
It was his extra-time penalty kick that proved to be the difference in the play-off final against Wembley, but he has played just seventy-seven minutes of league football since.
Since making his senior debut for Watford in the 1994/95 season, the former England international has racked up almost 650 first team appearances.
Arguably the highlight of his career came during the 1999/2000 season where, with Sunderland, he secured the European Golden Boot after hitting thirty-six goals and in doing so helped the club to seventh place in the Premier League.
The 40 year old has also had spells with Aston Villa, West Bromwich Albion, Southampton, Birmingham City and Blackpool.
