New West Ham United co-owner David Sullivan says Gianfranco Zola's job as manager is safe.

Sullivan and David Gold have completed their takeover of West Ham.

"He (Zola) is staying, and I will be sitting down with him to work on some transfers as we realise as fans that the team needs a few additions," said Sullivan.

Sullivan also said that he and Gold would welcome additional investors.

"I say to anyone else out there, if they want to get involved they are most welcome. It's a long-term job and we want people to come and join us. We welcome other investors."
