Gill joined Manchester United PLC in 1997 as finance director. In August 2000, he was promoted to deputy chief executive whilst retaining his responsibilities as finance director. In July 2001, Nick Humby was appointed finance director of Manchester United PLC, so Gill was promoted again this time to the title of Group Chief executive 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).
