Some of your gameplay decisions are frustraiting.
Most notably the ability to score on yourself as the goalie by simply turning around. More than a couple times, I found myself down a goal because I was chasing after an attacker, and when the goalie got it, he would turn around and score on himself because I had my mouse below the goal in the first place. The AI is kind of brutal, and the player selection can be pretty dense especially when you want a defender and accidentally get a winger nowhere near the ball. It's small things like that that kind of hurt this game.
