Essex say a decision on whether Graham Gooch will leave the club to join England's coaching staff full-time will be made in a "couple of weeks".
Gooch shares coaching roles between Chelmsford and England, but reports suggest he is set for a permanent switch to the national set-up.
"We're not sure," Essex head coach Paul Grayson told BBC Essex.
"He's enjoying his time working with England and I know he enjoys working with Essex as well."
He added: "It's just getting the balance between whether he's going to continue working with us or he's going to commit full-time to England.
"But something will be sorted out I would have thought in the next couple of weeks."
Former Essex batsman Gooch is England's all-time highest Test run scorer, hitting 8,900 runs between 1975 and 1995.
He was appointed England batting coach for the 2009-10 Test series in South Africa and the national side's batsmen have excelled under his tutorship.
Alastair Cook, Jonathan Trott, Kevin Pietersen and Ian Bell have all hit double-hundreds for England since Gooch's arrival on the scene.
