Head of the A-League Damien de Bohun has resigned, after four years in the top job, citing family reasons as the catalyst for his decision.

De Bohun's family is based in Melbourne, while FFA headquarters is based in Sydney, with the constant travel taking its toll.

“Damien brought incredible energy and dedication to the task, which spans a huge range of sporting, business and regulatory issues," FFA CEO David Gallop said.

"Running the A-League is a seven day a week undertaking. Damien did that while travelling across the nation and New Zealand to be on the ground with clubs to better understand their key issues and environment.

“I totally understand his decision to return to Melbourne and wish him all the best.”

De Bohun, who will remain in the role for the remainder of the season, is the longest serving head of the league since its inception.

“What is most important is that the Hyundai A-League has become a part of the mainstream of Australian sport over the last four seasons," said de Bohun.

“From the outset this role has been exhilarating, with some of the early highlights being the Wanderers taking the A-League by storm and winning the AFC Champions League,  and the marquee players like del Piero, Heskey, Ono, Kewell and Villa giving the competition genuine star quality.

“The real focus, though, has been to work closely with the ten clubs and the vast array of other key stakeholders including broadcasters, A-League players and coaches, sponsors, stadiums, media and most importantly fans to create a stable and sustainable competition. We have achieved that today and I am very pleased that the Hyundai A-League is in a solid position heading into a new period of opportunity and growth.”
