A club press release said that Addison left after a review of budgets in all areas, after the early exit from the FA Cup, and poor gates at The Lawn.
Addison said before leaving: “After much careful consideration, following discussion with both the Board and my family, it was agreed, prior to the match at Telford on Boxing Day, that I will today leave Forest Green Rovers Football Club by mutual consent. This is in view of the Club's huge financial commitment to the proposed new stadium and in order to assist Forest Green Rovers in fulfilling their ambition to achieve Conference success in a new venue, that will benefit the Club itself and the wider community.
I would very much like to express my appreciation to my two assistants, Tim Harris and Paddy Mullen, for their great support, along with that of the players and the backroom staff for their tireless effort and commitment to the cause. My thanks must also go to the Chairman, Directors, Administration and Ground Staff; to Clive for his assistance in the preparation o my programme notes; to all my friends in the Green Room, Social Club and Supporters Club, for their endless hard work and to all Forest Green Rovers fans for their support. May I take this opportunity to wish you all very happy healthy and successful 2004”.
