Manchester United are expected to announce this week that David Moyes' doomed tenure at the club cost them an eye-watering £50 million, according to the Telegraph.
The former Everton boss was handed a six-year contract to take up the reins following Sir Alex Ferguson's decision to retire in 2013 after 26 trophy-laden years at the helm at Old Trafford.
However his time in charge of Manchester United proved to be a disaster as they recorded their lowest ever Premier League finish, while Moyes was eventually sacked four games before the end of the season - just 10 months after he had been appointed.
According to the Telegraph, Manchester United executive vice-chairman Ed Woodward will make an announcement about the club's finances on Wednesday, and while he expected to show that the club is in rude financial health, the true cost of appointing Moyes will also be revealed.
His failure to guide the Red Devils to Champions League qualification meant they missed out on around £35 million in revenue. Their lowly league finish meant they were down just short of £9 million in revenue generated from the Premier League, while his wage packet and subsequent pay-off come to about £7 million. Compensation paid to members of his backroom staff who were let go will also be included which puts the price of his appointment at well in excess of £50 million.
Despite that gaping hole in their finances, Manchester United will announce revenues well in excess of £400 million for the financial year, making them one of the most successful clubs in the world.
Despite their on-pitch failings they can boast one of the most lucrative sponsorship deals ever with Adidas, while agreements with Aon and Chevrolet have further boosted the coffers.
Their ability to generate cash was evident during the summer window when they splashed more than £150 million on six new players and broke the British transfer record by forking out £59.7 million to take Angel di Maria from Real Madrid.
Their spending isn't expected to stop there and they reports say boss Louis van Gaal will be given another £50 million when the January transfer window opens up.
