Because win bonus or changing formations and tactics doesn't make you win, because the game is fixed before the match as some of are said it earlier,
Me & my friend did a experiment in officially league game,
I played with my usual formation & tactics( my team was at the top place and never loss a league game)
His team is not in good form despite having a good players,
He changed his all tactics( Hard attacking, low pressing, easy tackling, long ball passing, man to man marking, he removed win bonus, we both were present in match,
My players missed many easy chances, at the time of half time score is 0-0
My friend missplaced his players after 45 mins, but still my players missing a lot of chances, my team scored 3 goals after 80 mins, so the changes my friend did in his team when the game was going on it applied very late? & the tactics he used is stopped my team why?
I Still have to do lot of experiments
