"Gordon and I have fully discussed the situation and are comfortable with his decision.
"Despite the fact that we may appear an unlikely partnership, I have very much enjoyed working with Gordon over the past two and a half years.
"His enthusiasm and commitment have inspired everybody and the club has moved forward during a crucial period after leaving The Dell and moving to the Friends Provident St Mary's Stadium.
"Gordon has assured me that he will give 110% for the balance of this season in order to capitalise on our current position in the league.
"Our fans will be sad to see a man, whose passion matched theirs, taking time out of the game."
