"During my eight years as manager I have enjoyed some great successes. Most significantly taking the club back into the Premiership, finishing fifth and qualifying for Europe after a 20-year absence.
"I was delighted to be recognised for these achievements with both the FA Premiership Manager of the Year Award and the Managers' Manager of the Year Award.
"I would like to thank all the Board, staff and players for their loyal support and in particular to our fans who have supported me tirelessly throughout my time as manager.
"It has been pleasing to see supporter levels grow from an 11,000 average in my first season to an average of 25,000 fans today.
"I am proud of bringing through some of the best young players in the country such as Kieron Dyer, Richard Wright, James Scowcroft and, this season, Darren Bent and Darren Ambrose.
"Over that time I have bought players from lower leagues and developed them into regular international players such as Matt Holland and Hermann Hreidarsson, whilst continually having to generate vital income through the transfer market."
