Game is like rolling dice, you never know what will happen. If you want skills to make a difference, I think you should quit. As I have discussed previously, my unmanaged team, in terms of results (wins/draws/losses) is almost as good as my managed team. The key difference is that my managed team is stronger and tends to win certain key games in the cup or CL. In terms of the league, my unmanaged team has yet to lose a single League.
The game engine is useless and trolls players regularly but Nordeus doesn't care about player experience. They just want to make money. If they cared, they would have improved the system after seeing over 100 pages of people complaining about trolls.
Otherwise, people on here will either (a) agree with you but they can't do anything about the trolling either or (b) reach for straws as they try to argue that the game involves skill and there is something you aren't doing right.
The reality is that the game involves very little skill. Ironically, players admit this when they recommend that you weaken your team at the end of a season in order to get drawn against weaker teams and then just strengthen the squad. This is the equivalent of using a cheat code and then claiming you beat the game. Having a stronger team and a valid tactic will help you win 85% of the games. For the rest, just hope that the inevitable trolls don't cause you to forfeit the title.
