It depends on the analysis what people are going to bet on. If some teams have had matches before and the stats are seen by the betters then the analysis will rule the bets. If then any one of the bookies do a match fixing with the teams and then the fixing turns out properly, then its a huge profit for the bookies. This is true in most matches these days but also many matches are done in clean way as well.
Agree with both. All football clubs will not do so, because after all all all football clubs already have own funds in order to pay or raising the prominence of the Club. So gambling sports does not have anything to anything against any existing clubs, so think laterally. Advantage Club is much larger compared to games made by all the people who do it. And the negative thoughts will destroy your profits
