What have I learned from last season?
That it is a totally random game. As somebody mentioned it is more about the form then about the quality. I learned that it is possible for 8 players to loose their form drastically overnight (aka update) to go from 7-8 scores to 4-5 scores. Was doing well in the champions league and 2nd in the league at that point.

What did I achieve?
Next round I was out of the champions league where I had the memorable game with 25 shots and 12 on goal to not score a single one. I ended up in the 8th place in the league. After loosing my forlast game against the bottom feeder with 2:0 I thought screw it. I put in all my replacements with no morale whatsoever. My quality dropped at least 5-10 points. Didn't insert a win bonus and I lost the game against the second of the league with only 1:0. What a complete BS.

What do I hope to learn in next season?
More about the randomness of this game. The cup matches were lost against a player of a level higher. It happens. Again bad scores. First league match was a win and my scores went finally back to normal. Last game my star AML scored the first goal and scored again another 5 (solid 8-9 player first half of the former season).

I replaced my 3 MC to get better scores and I hope they will keep on getting the good scores.
