Disadvantage if I don't spend money on the game. Ai sheet

I feel like the game interferes with the game, when I start my attack it does something else to prevent the goal situation, helping the opponent, every ball bounces to the opponent. It allows goals unpredictably. It ruins the situations if I play with weaker players and brings the game to an equal position. If I don't buy anything for a week then the game is very sluggish in champion.
