After a two-year spell in San Francisco, he left the firm in 1986 to join BOC in its corporate finance department, and then Avis in 1990.

Subsequently, he was Finance Director at Proudfoot, the worldwide management consulting business, then quoted on the London Stock Exchange, and then at First Choice Holidays, the third largest UK tour operator, before joining Manchester United in 1997.

In July 2001, Nick Humby was appointed finance director of Manchester United, so Gill was promoted again this time to the title of Group Chief operating officer, allowing him to concentrate on managing the day-to-day operations of the business (including sponsorship & marketing, business development, financial services, conference & catering, ticketing & membership and group property).

However, in September 2009, he was elected to a two-year place on the board of the European Club Association, the organisation created to replace the G-14.

[4] On 20 February 2013, Manchester United announced that Gill would leave his post as chief executive in the summer of 2013, but that he would remain on the board as a director.

Questions were raised by Liverpool manager Rafael Benítez about a potential conflict of interest between Gill's roles with Manchester United and the FA.

"I simply do not see how there will be change for the good of world football while Mr Blatter remains in post" Gill stated.
