West Ham have announced that midfielder Jack Collison has penned a new long-term deal with the club.
The 22-year-old has been with the Hammers since the start of his professional career and has become a central figure in the side.
There had been speculation he could leave Upton Park following last season's relegation, but skysports.com revealed earlier in the summer he had entered into contract talks.
An extension has now been signed and the Welshman is delighted to have committed his future to the club.
"Obviously it's great for me personally to know that I can now get my head down and concentrate on my football," he told West Ham's official website.
"That's the most important thing for me to do now - get my head down, do my business on the pitch and have a good season.
"It's nice to have the security of knowing my future is with West Ham United. I look around and see what they are building and I want to be part of the future. Fingers crossed, I'll work hard and hope I can do the business."
Collison has only recently returned from a long injury lay-off and knows he faces a fight for a regular starting berth under Sam Allardyce.
"We definitely have competition for places in the midfield, but that's what you want because it brings the best out of everyone," he added.
"We're all fighting to get into the starting XI, but it's a long old season and the manager has already said it's about having a good squad and a big squad and we feel we have that here and we are working together and looking to get promoted."
