Note that for Liverpool and Tottenham, they might have won on a fluck, which is why some results aren't terribly surprising. The issue people have is that they feel cheated by the fact that the simulator somehow pre-determines they are going to lose.
Just had to play against two teams in my league. Both teams are 95%, I am 114. I beat both those teams the first time around. We used the same tactics and I dominated both games. I played my normal counter attack, 4-5-1v style with defensive tactics and defensive bonus.
Game 1
We went from 2-0 to 1-1
Commentary - We just weren't lucky today. Note: Manager wasn't there, I had full bonuses and had +15% for attendance.
Game 2
We went from 3-1 to 2-3.
Commentary - Our GK didn't perform. The opponent really impressed. Note: Manager was present but I had +3% bonus.
The worst part was that I took the lead after 25 min and was leading 2-0 and then, an incredible thing happened: he scores 3 goals on counters, even though my team instructions were to defend. WTF??!?!?! How does a team that is set to defend get caught 3 times on counter???
The end result is that now, in my league, I am tied with the second team in terms of points, but I have twice as many goals scored. Also, in 2 games, I was scored twice the number of goals I conceded in 13 games.
This is exactly the problem with the game. When the simulator has determined you are going to lose, it doesn't matter (1) what you actually do or (2) what you have done (i.e. trained your players and put all bonuses on your side). These results feel like the simulator said: "You are winning the league too easily, therefore you need to lose these games to make it exciting."
