West Ham United boss Gianfranco Zola has been ordered to submit a report to the board about how he plans to keep the club up, it has been revealed.

The Daily Mail says Zola has been ordered to present what amounts to a survival dossier to co-owners David Sullivan and David Gold outlining exactly how he plans to save West Ham from the drop.

Zola is said to have clashed with Sullivan at the club's training ground yesterday.
