West Ham United first-team coach Steve Clarke has joined manager Gianfranco Zola in signing a new contract to stay at Upton Park until 2013.
Clarke joined Zola at the Hammers when the Italian took over earlier this season and helped guide the Londoners to their current position of eighth in the Premier League.
Zola extended his deal on Saturday and Clarke, 45, has followed suit on Tuesday.
"I am delighted, I have had a great time since I came here. We have done okay," Clarke told the club's website.
"There is a lot more still to be done and the contract reflects that.
"It is a long-term contract and what Gianfranco and myself and the rest of the coaching staff look forward to is improving things and working hard every year to make things better and better at this football club."
