James Collins has agreed a two-year contract extension with West Ham.

"To be signing for another two years, I can't explain how happy I am to be part of a club that is moving forward and getting bigger and bigger, so to be part of that is unbelievable," the 32 year old said on the club's official website.

The Wales international added: "I'm obviously delighted to sign, as it was worrying me a bit that I'd have to leave again.

"I try to be professional, as I've been in teams where players make a negative effect when they're not playing, so I am just proud to be part of such an amazing club.

"I'm happy coming in every morning, whether I'm playing or not playing, and I train hard and try to keep myself fit.

"To be part of such a big club for such a long time, I'm a very lucky boy.

"To sign for another two years is something that, to be honest, looked doubtful at the start of the season, so I got my head down and trained hard and tried to show what I could do."

Collins admitted the prospect of West Ham's move from Upton Park to the new stadium on Queen Elizabeth Olympic Park next summer spurred him on to push for a new deal.

"It's massive and that was the biggest thing in my head, really - to be part of something that is moving forward and is so big," he added.

"The thought of not being involved in it was getting me down a little bit.

"The thought of not being involved in this club, and with the fans who I have got a special relationship with and have always been great to me, was playing on my mind.

"As soon as I knew I could get a chance, I had to perform to be involved in that, and fortunately that's what has happened."
