LONDON – Sir Alex Ferguson’s earning power shows no sign of weakening even though he retired as manager of Manchester United five years ago after winning 38 trophies over 27 years.

New accounts reveal that the Ferguson family company ACF Sports Promotions Limited made a profit of £2.3million last year with reserves rising from £7.049m to £9.385m. Sir Alex, 76, and wife Cathy are directors of the company along with their three sons Jason, Mark and Darren, who are the sole shareholders. The business was set up in 1983 when Ferguson was Aberdeen boss.

Sir Alex’s main earning stream remains his lucrative role as a United ambassador, for which he is paid £2m a year for 20 days’ work.

He can also earn £100,000 for public speaking appearances and business seminars — on a par with former US President Bill Clinton. Both men are on the books of the renowned Harry Walker agency.

Jason, a former football agent, represents his father while Darren is manager of Doncaster Rovers and Mark a city financier.
