Gianfranco Zola has extended his contract as manager of West Ham United after signing a new four-year deal on Saturday.

"I'm delighted to have signed the contract," Zola told the club's official website.

"I'm very pleased and grateful to the club for looking after me. We have a project that we are taking forward with the coaching staff and with [sporting director] Gianluca Nani and [chief executive] Scott Duxbury."

Duxbury said that he expects assistant Steve Clarke to follow Zola's lead very soon.

"We hope we can achieve success this season but we're very much looking at the long-term with Gianfranco," he said.

"With Steve Clarke soon to sign we know we have the foundation for great success. It is a very bright future for West Ham."
