Just checked the odds on Skybet and they have us at a ridiculous 2/9 to win the Prem (second favourite is Spuds at 10/1). I know we've been brilliant so far, but it's not even November yet ffs!
However, the long odds on everyone else does mean that a 30 quid bet (a tenner on Spurs, a tenner on United, and a tenner on Chelsea), would cost you 30 quid if City won the league (good value!) but if somehow things went wrong (i.e. FA/PiGMOL conspiracy), you'd win 80 quid (Spurs), 90 quid (United - I feel dirty typing that), or 200 quid (Chelsea).
The nightmare scenario in this plan would be if Arsenal or Liverpool somehow won the league (hard to keep a straight face typing that). But if you're the paranoid type, another tenner, split 5 and 5 between those two would net you almost 300 quid for an Arsenal win or nearly 500 quid if it is, indeed "their year" (again).
