Avram Grant is hoping Matthew Upson will follow the lead of West Ham United team-mate Scott Parker by signing a new contract.
Influential midfielder Parker tied up a new four-year deal at Upton Park on Thursday and the Hammers now want Upson to commit his future to the club.
The England defender's current deal expires at the end of the season and talks have taken place regarding an extension.
Hammers boss Grant wants the 31-year-old to stay at the club and says finances will dictate whether Upson accepts a new contract.
"The club have given him an offer, they are in negotiations," Grant confirmed.
"The club want him to stay, but it's a matter of money."
Meanwhile, the build-up to Saturday's match against Chelsea has been overshadowed by comments attributed to club co-chairman Sullivan, who was reported to have said a number of the squad's foreign players "couldn't be bothered" to play for the club.
Previous manager Gianfranco Zola came into conflict with Sullivan for his public criticism of the players last season, but Grant insists he has no problem with the 61-year-old.
Grant said: "First, the owner didn't say that. Second, for me there is no foreign players or English players. For me there is a team, everybody is a football player for me.
"He is the chairman and if he wants to do something he can do it as long as it doesn't hurt the team and I don't think it hurts the team.
"We have a good relationship and I need to do my job, not to look at what people said."
