I doubt it. They may pretend to be shaken up, but they aren't. Betting on EPL is huge. They paid out £8 million on Leicester winning, but I bet (no pun intended) that it hardly makes a dent on how much they made from winning every title bet on the other 19 teams. It would be interesting to see the actual cost impact of Leicester winning vs. the other teams. I'd guess that bookies would've had to pay out more than £8 million if Man City, Man U. or Arsenal had won. On top of that, they have won on thousands of long shot bets over decades, and now there will probably be even more suckers to their lose money on ridiculous long shot bets.
