The 29-year-old has just one year left on his contract with the Hammers and has still not been offered a new deal.
Gold said: “At this stage we are not going to have talks with him about a new deal.
“World Cups change lives. It’s the global shop window and who knows what may happen. We could get amazing offers – offers you can’t refuse.
“What do you do if Manchester United or Real Madrid, for example, come in offering millions of pounds?”
Avram Grant has replaced Gianfranco Zola at West Ham.
Gold added: “We have to see how Robert feels and consider the new manager’s view.
“He will take the squad on a pre-season tour and judge Robert with everybody else.”
