West Ham boss Zola has not spoken to Sullivan for weeks
The Mail on Sunday says Zola not spoken to club owner Sullivan since asking him to leave a meeting with players a month ago.
He said: "There is no point talking about the future. It is important to sort this situation out and then we will deal with the rest.
"We haven't spoken about beyond the end of the season. We said some time ago the best thing to do is to focus on this season and get the best out of it."
