I know everyone has their own strategy and somehow most people can be using same strategy that I am about to share here.
The strategies includes:
1. Club position: most times the position of a club matters a lot because it tells you whether a club is striving to top the table or whether they are striving to leave relegation zone.
Picking a club to win a match by their league position is a good strategy for one to use to pick bets but not always does such strategy work. There are times when top clubs lose to lower clubs in the league table. We have seen that happen on several occasions.
2. Point: This is another strategy i use while betting because it also tells you whether a club can or will loss a match or not, sometimes a club can be topping a league with 8 -10 point difference and because of this point difference they can decide to play anyhow they want better still reserve players for more important match because whether they loss or win they are still topping the league.
However, a club that has this point difference, let say they are expecting a champions league quarter or semi finals, it is very possible that they can loss or draw their league by reserving players for the upcoming champions league.
I don't accept this "a club giving less energy to match because they are leading with 8-10 points''. A club topping the league table with such points won't like to lose their match when the league matches haven't gone far(when there are so many matches to play). The only time I know that such a thing will come into play is when a few matches are remaining to end the league season.
3. Head to head: a club head to head (history) is very important because sometimes it could be that the people topping the league always loss or draw with the people fighting to go out of relegation. No matter how form the people topping the league is the possibility or chance of losing the match is 80% because of their history that's why sometimes you see a big club always losing to a small club.
It works at times, but not always.
In a nutshell, football betting is about being lucky to win a bet because the way you plan a football match to end in favor of a club, doesn't end as predicted. So betting less with money you can afford to lose, is advised.
