NANI'S last-gasp winner left bookies reeling as Man United hit back from 2-0 down to win the Community Shield.
Despite the five-goal thriller I was spot on with my prediction that the first goal would be scored after the 31st minute. That paid 23-20 with William Hill.
Bookies were preparing to toast a penalty shoot-out with moments to go until United snatched victory to give favourite backers the first spoils of the new season.
Ladbrokes spokesman David Williams said: “It was very nearly a brilliant afternoon. West Ham's defeat and the Wembley draw would have been as good a day as we could have hoped for.
“But Nani's goal was a shocker. It signalled a massive turnaround for the punters who were all over United and they've drawn first blood.”
William Hill have cut United from 8-15 to 1-2 to finish above City in the Premier League this season. City are 1-3 with Hills to end the season with one of the major trophies while United are 4-5 to do likewise.
Hills, who were offering United at up to 18-1 in-play to come back from two behind to win, were also left cursing Nani's late strike.
Spokesman Graham Sharpe said: “With seconds to go we were congratulating ourselves on a six-figure winning draw and seconds later we were looking at a six-figure loser.
“We took a total of £960 for United at 18-1, including one of £100, then one online punter from Scotland was confident enough to stake £1000 on the comeback at 16-1 and another had £500.”
United keeper David de Gea was criticised for his part in City's second goal and Hills have opened a book on how many Premier League goals he will start this season. They offer 29 or less at 6-4, 30 to 32 at 4-1 and 33 or more at 10-11.
Meanwhile, after West Ham's shock defeat to Cardiff boss Sam Allardyce is 11-4 with William Hill to be gone by the end of the season (1-4 to remain).
Leicester are now clear Championship favourites at 7-2 withHills followed by West Ham 9-2, Ipswich 12-1, Cardiff 14-1 and Blackpool, Brighton and Forest 16-1.
