Permit me to say, sir, that your 8 years of experience have nothing to do with being able to know the outcome of matches. If prediction was sure, then it wouldn't have answered the name "prediction." Since it's all a matter of luck, that is why it's called prediction. BTW, there are so many prediction sites that are sometimes very accurate, but yet they fail so many times on different predictions. whereas teams are working together to predict the outcome of games, compared you to an individual prediction over a whole series of games. How possible is that?. 

There is nothing like a sure game. I used to say that I have sure games, but I did realize that even if you are dead sure of your predictions, this match will go against your predictions because even the soccer player won't be able to tell you boldly that they will win. So your analysis can be correct at times, but your advertisement could be used for yourself if you are so sure of your prediction.
