First I shall apoligise for using soccer & football throughout this document together. But as this is the internet it will be read around the world and despite the fact the English invented Football it is now referred to as soccer so I will use both for the benefits of readers around the world.
After many years looking at football matches and coming to understand the mathematics behind them I can now predict the probabilities on almost any match. Not only that but I can continue to predict the match while it is in play. During my huge amount of research on soccer / football matches I have discovered many prejudices against or for certain situations that occur in football matches. I would like to explode a few of those for you and go on to talk about things in a very general sense.
I have analysed soccer matches since I was knee high to a grasshopper and have accumulated unbelievable amounts of data to do with matches. I think I probably started to seriously collect data in the early 1980's but my interest pre dates that to when I used to play table football and even then keep accurate records of those matches! A very long time ago I started analysing what happens inside a match as this obviously had a large bearing on the final result. I didn't know why I did that but I was glad I did as many years later I was able to use this data in the modern betting exchange markets. I can't think of many things I haven't looked at over the years. If there is something you wanted to know about a football match I have probably studied it at some point.
Common soccer myths, conundrums and the answers to them
There are various pointers you can use to determine the flow of a match. I have used rounded and general data here so don't take these statistic as red. There are endless combinations and permutations of odds and their use and combination.
Home advantage - Does exist and you can see it clearly by analysing any quantity of football data. The home team wins generally 45% of the time, draws 30% of the time and the away team wins 25% of the time. On average there are around 2.60 goals scored per game favouring the home team. Home advantage is generally reckon to be worth around 0.40 of a goal in terms of supremacy against the opposition.
Likely scores - If the home team wins; it will win 1-0, 2-0 or 2-1 over 60% of the time. If the away team wins if will win 1-0, 2-0 or 2-1 nearly 70% of the time. If its a draw is is highly likley to be 0-0, 1-1 or 2-2.
If you wish to work out on average who is going to score first in the match take a coin out of your pocket and decide on heads or tails while you flip it in the air.
If the away team scores first the chances of the match ending in a draw goes up. If the away team equalises after going a goal down then there is still a high probability that they will not go on to win the match. So don't panic if your team playing at home squanders an early advantage.
Don't bother turning up for the first half!!
Nearly 1/3rd of matches are 0-0 at half time. All the action is in the second half!! It the match is 0-0 at half time the odds on a draw have risen quite a bit usually at the expense of the home teams chances of winning. So 0-0, if you are playing at home, is bad and away is not bad but not particulary good either.
If the score is 0-0 at half time it is critical that your team scores first in the second half. If you do there is only a small chance of your team going on to lose the match.
If your team is playing at home and is losing at half time then they must score first in the second half or else they have little chance of winning.
Even if your team is dominant and has more shots towards goal there is still a one in four chance that they will not win a match. It is true that teams can play well and still lose thanks to being unlucky. So don't be too hard on your team when they fail to win.
And finally............... NEVER, NEVER, NEVER, (Have I made that clear), NEVER, leave the ground early under any circumstances!! The probability of a goal in the last minute or in extra time is actually quite high. Much higher than most people suspect. OK so it could go against you but there is a slightly better chance it will be for the home team. So stick around and enjoy that pleasure of a late goal. After all you could savour it while stuck in traffic on the way home because you didn't leave early.
I hope that gives you something to chew over. All the above probabilities are general and spread across the entire spectrum of matches. Individual matches vary significantly based upon the ability of the teams.
