It's often problematic... you see a sure win game, the best team plays with the worst. Odds for the better team are around 1.2 or 1.15... But I will give you some advice how to make substantial profit from this situations. I use this methodology a lot and it's very profitable.

Try to search on Google statistics about when goals in a football game are scored most often. It's really not hard, but you should notice, than no matter what the league or competition is, goals are more often scored in the second half of the game. Yeah, great but how to use it..?

Now look at this big games on live betting. What you should notice, the game starts from 0-0, and the favoured team isn't ahead from the start. And they rarely score in first minutes. During the time, odds for the better team start to rise.. From my observations, from odds 1.2 when a result is 0-0 after the first half odds are around 1.45. When the result is still 0-0 around 60 minute of the game you can bet on the better team at around 1,8... WOW I would say.. Considering the statistics, and that the underdog would be more tired within time and more likely to make mistakes it's a great opportunity.

I will give you some examples of my play:

1 December 2007 Chelsea - West Ham odds at start 1,3 for Chelsea. Staked Chelsea at 56 minute @1,78 on Betfair, result was 0-0. Final result 1-0, goal in 75 minute.

24 November 2007 Arsenal - Wigan odds at start 1,2 for Arsenal. Staked Arsenal @1,45 after the first half, and @1,73 around 60 minute on Betfair. First goal scored in 80 minute, final result 2-0

24 November 2007 Barcelona - Huelva odds at start 1,17 for Barcelona. Staked Garcelona @1,5 after the first half on Betfair. First goal scored in 50 minute, final result 3-0

I don't say it's a way to win all the time, but the probability will be on your side.
