Former A-League chief Archie Fraser will be unveiled on Tuesday as the inaugural chief executive of incoming expansion club Macarthur-South West Sydney.

Fraser, who has been working with the Association of Australian Football Clubs towards the establishment of a national second division, will instead divert his focus back to the top tier of the game with the new A-League side, who enter the competition in the 2020-21 season.

Macarthur-South West Sydney have scheduled an announcement to be fronted by chairman Lang Walker and deputy chair Gino Marra. It's understood Fraser will be unveiled at that press conference after beating a field of candidates, which included former SBS journalist and one-time Football Federation Australia media boss Kyle Patterson.

Fraser was head of the A-League between 2009 and 2010, a turbulent era in the game which saw the disastrous introduction of short-lived expansion clubs North Queensland Fury and Gold Coast United. Before that, he was CEO of AFL club St Kilda for three years and oversaw their controversial move away from their spiritual home at Moorabbin to Seaford. The Saints have since moved back.

Fraser also memorably jumped on board with 'Football Australia', an attempted breakaway federation established by Clive Palmer in 2012 as a response to FFA's decision to strip Gold Coast United of their A-League licence. He has become a boisterous critic of FFA and of the A-League in recent times.

Born in Scotland, Fraser is a former professional footballer whose candid, sometimes aggressive nature is part of what prompted Macarthur-South West Sydney to appoint him to the role.

Macarthur-South West Sydney is due to unveil their playing name, colours and logo at a gala luncheon in Campbelltown on May 15.
