United were cut from 11/2 to 5/1 following the news that Mourinho has signed a three-year deal at Old Trafford with the option of a further year.
Mourinho’s track record – he has won domestic titles with Porto, Chelsea, Inter Milan, Real Madrid – suggests results will come quickly and bookies and punters certainly appear to think so.
On the day Leicester won the title earlier this month, United could be backed at 7/1. Just over three weeks on and they are a full two points shorter.
Reigning champions Leicester are a best price of 25/1. They had been on offer at 33/1 the night they completed their remarkable 5,000/1 2015/16 success.
United are odds-on at 8/15 for a top-four finish. City, Chelsea and Arsenal are also odds-on in that market.
Mourinho is 5/2 to see out his three-year contract.
It’s also 6/1 that United complete a home-and-away double over his former club Chelsea next term.
People have really been getting excited about United and as such they’ve moved several prices in the betting. They were as big as 8/1 at the beginning of May and are now 5/1 with the business still coming in pretty quickly.
Despite all the money for United under their new boss, Mourinho arguably faces the toughest job of his career if he is to turn them into English champions.
In many of his his previous jobs, he has turned a very good side into a slightly better one.
He took over at Chelsea after they had finished second and made them champions in his first season; Inter were already Italy’s top side when he arrived at the San Siro, while Real only moved from second to first during his spell in Spain.
United finished fifth last season – a full 15 points behind Leicester.
However, Mourinho did take Porto from fifth to champions in 16 months when he took the reins at the Portuguese club back in 2002.
