Remember on the exchange your stake is included in the decimal odds.... I've explained this a few times just today,in fractional odds we are 1/86 on to finish in the top six (Betfair exchange odds converted to fractional)... The 1.14 decimal odds on the exchange is the sharpest price you can currently get. 1/100 on ( in fractional odds ) is the best you can get from a sports book.
For what it's worth I never bet on football.... you can never find an overlay .
For anyone who likes to bet on Football, always check Pinnacle odds lines you can't bet with them from the UK but they have the sharpest odds compilers....if you find a sports book offering higher odds than Pinnacle in any football market you are at least getting value.
