This is one of the big bad sides of this game. Suddenly a team can go on a bad run for like no reason, and the match just goes like to how the game engine wants. Opposition goals come out of nowhere, team draw or lose even if they are stronger, properly managed and even if they dominate those matches statistically. In one past case of mine, I can say that this occured because the game wanted another team to win the league, and the game trolled in so many ways so that in the end my team lost the league by goal difference despite that I was better tactically compared to the mananger that won the league and I even beat his team on his ground.
Despite having played this game for a long time, I myself do not know for sure what can be done to avoid this other than maybe spent fortunes in the game.
