It's not enough for a team to be favorites in a match – or for you to be sure that result will happen – for it to be worth placing a bet on a particular game. The analysis of
odds is a key factor when determining whether or not you should put your money into that opportunity.
A good way to start analyzing an odd is to pay attention to how much the house is offering the least likely outcome – that is, the underdog.
To find out if the odds offered are at a fair value and, more than that, interesting to place a bet on football, you can use some sources:
Past odds of the competition and the clubs involved
The odds offered for the same game in other houses
Your knowledge of the championship in question
Imagine that you are going to place a bet on Arsenal vs Liverpool, in the English league. If you are used to watching and betting on the Premier League, it will be much easier to define if the odds offered by the bookmakers for that game are attractive.
