West Ham United boss Gianfranco Zola is set to walk if Massimo Cellino is successful with his takeover.

Zola does not get on with his fellow countryman and would walk out if Cellino beats David Gold and David Sullivan, Malaysian Tony Fernandes or the InterMarket Group in the race to buy the club.

A source close to Zola revealed to the News of the World: "If Cellino's bid is successful, Zola will go.

"There is history. When Zola left Chelsea he went back to play for his home town club Cagliari then owned by Cellino.

"Zola is a man of honour and agreed a verbal two-year deal.

"He helped win the club promotion to Serie A. As soon as that happened, Cellino felt Zola had done enough for the club and didn't want to continue the deal.

"Zola was furious. So were the fans. It was only their outcry which saw Zola stay. Zola is a Sardinian. He has his principles. He wants to do well for West Ham. But he will not work for Cellino."
