The investigation found that Ferguson was paid £2.165m in the eight months to June last year after signing a deal to become a global ambassador for the Red Devils. The contract that holds Ferguson to the club states that he must work 20 days a year to be paid, meaning he earns a stunning £108,250 a day.
Few would argue that Ferguson deserves to be looked after in his retirement. His commitment to Manchester United helped to establish them as one of the biggest clubs in the world. He brought 13 Premier League titles to the club in a 26-year reign amongst a host of other trophies.
However, such a rate would make him the most expensive asset on Manchester United's books, at least if you judge it on a day-to-day basis. Angel di Maria earns a reported £280,000-a-week while Wayne Rooney is on £300,000-a-week.
Another report in The Guardian claims that Sir Bobby Charlton, another of the club's many ambassadors, earns £105,000 a year while Ed Woodward is the Premier League's best paid chief executive, earning a £2.521m salary.
Ferguson remains a director at Old Trafford and is regularly seen in the appropriate box watching over Louis van Gaal.

With Ferguson currently earning this princely sum for less than three-weeks work, don't expect him to come out of retirement any time soon.
