#3 It would be very expensive to sack him
Manchester United was significantly impressed with what Jose Mourinho had achieved in his first year at the helm of the club that he was handed a new contract extension in January.
The new deal made the 55-year-old further cemented his stock as one of the highest paid managers in the world, and apparently, his paycheck is so hefty Mou himself joked that United could not afford to sack him.
Football is big business, and like all other businesses, it's all about the numbers. The costs of severing the contract of a marquee coach in the mold of Mourinho is too exuberant, with pay-offs and compensation rising to figures as high as £12m.
The costs involved in terminating Mourinho's contract are really off the roof, and it would be in United's best financial interests to let him get on with his job.
