The 32 year old – once described by former boss Harry Redknapp as the most exciting youngster ever to pass through his hands – made an emotional return to the Boleyn in 2013 January transfer window.
He made made 37 appearances and scored five goals since rejoining the Club in January transfer window.
We understand that Joe has offers on the table from the MLS and that Queens Park Rangers may be ready to offer him a deal.
But he is clearly emotional at leaving the club that reared him and told www.whufc.com: “It’s a great club. Returning West Ham, it was a fantastic opportunity to play for the club again.
“We finished 13th this year and we’d have liked to have finished higher, but we move on and hopefully next season they’ll continue to keep their place in the Premier League and move onto a top-ten finish.
“Every day is great to play and train at West Ham. It was a pleasure to play with the lads and I can’t thank them enough, they were fantastic.
“The fans are always great with me and I wish them all the best for the future.”
Everybody at ClaretandHugh thanks Joe for his wonderful service to this club and who knows, one day he might return in some role or other – we hope so!
