Head coach Mark Davis is set to follow long-serving batsman Chris Nash out of Sussex.

An internal review of a disappointing season, conducted by chief executive Rob Andrew, exposed disunity over the way Davis has been running the team.

South African Davis, 46, became head coach in November 2015 when Mark Robinson left to coach the England women's team.

The former Sussex off-spinner and second team coach has failed to steer the county back to the top flight of the County Championship.

They have finished fourth in the second division twice and missed out on qualifying from the group stages of the limited overs competitions.

Davis has been associated with Sussex for 16 years.

His imminent departure follows this morning's announcement that Nash has left by mutual consent, with a year remaining on his contract.

Nash was disappointed to be overlooked for the captaincy after his close friend, Luke Wright stepped down mid-season, and is poised to join another club.

Nash, 34, has been with Sussex for 26 years.
