Honestly when sportsbooks gave Liverpool such a low chance to win and the odd was so high, I was a bit confused, after all I thought this is the team that lost only once (to watford!) and why would they lose now? Sure they have a "chance" to lose like in any game but it was over 3.5+ for Liverpool to win the game, it looked like it is nowhere near that impossible for them to win that game and the odd looked weird.
Now that I look at the result, maybe sportsbooks know this thing more than we do
. They actually allowed Liverpool to be that high so that people would find it lucrative and wager on it and they knew that City would be the better team on the pitch. The game ended 4-0, wasn't even close to being competitive and from the first half it was already decided, kudos to all odd providers.
The truth is that the sportsbook also get things wrong almost as often as they do get it right, Chelsea won against Man City just a few day before that and they were offered at an even great value, what would you say about that ? Of course the sportsbook probably do get a lot of informations about these games and it's used to determine the odds, but it necessarily doesn't mean it will always affect the result positively.
If you look at logically it is probably always in the odds providers best interest that the underdogs win, then providing odds that would almost certainly decide the winner of any fixture is directly in contradiction to that interest.
It is a game between the bookies (odds providers) and us the gamblers.
Bookies/odds providers have much better logistics and whole teams of people that work on stuff like creating the odds in a way to make them more appealing, sometimes even to purposely throw you in the wrong direction. Bitcoin bookies are in my opinion more "fair" then fiat ones in this respect. My favorite fiat bookie offers heavily boosted odds on few games which look like they have clear winners and often end up anything but easy. Then they make it mandatory that you have to play 6 pairs on multi in order to use those boosted odds. They even employ psychologist to read the mood of the crowd and boost their profits.
We, gamblers have a big advantage in choosing our own bets. While the bookies scout and make odds for 1000 games every day, they don't have time to do deep analyses and use algorithms to help them. We can take our pick of the games and do better job than them on those few selected markets and pounce when we find value odds.
Sportsbet is actually quite good in giving great value on odds for the customers in their specials. Try calculating the odds few times and you will see. I don't play them often but I look at them almost every day and take them when I find something I would maybe play even from regular markets.
