For about 15 years me and my friends are playing a soccer prediction game. In one of these years I try to create a model to predict the score of the game. As predicting the score is more difficult than predicting the result, my model resulted so bad than I thought.

While I was creating the model I include these factors:

• League positions of the teams and, goals for and goals against(gf/ga) according to home/away
• Last 5 matches between two teams and gf/ga
• Last 5 matches of the teams in the league and gf/ga

Actually the model was not bad when predicting the result, as it gives correct results between 40% to 60% but when it comes to score prediction it is not what i expect.
