The Value Premiership

How many punters bet with their hearts not their heads?
Do certain teams consistently represent good betting value?
Are certain teams constantly overbet?
What are the best and worst value teams to back in the Premiership?

We at Betfair were very interested in the answers to these questions, so we decided to examine the Betfair database, and it came out with some intriguing results.

We put an imaginary £10 bet on every team in the Premiership for this season to date and the last 2 seasons, placed at an average price in the last 2 hours before kick-off. Three teams came out a level stakes profit for all 3 seasons. Can you guess 1 of them?
