Actually, troll results rarely happens. Whenever my team perform badly I could find a reason for that most of the time and correct my mistakes. Whatever troll result you see are usually caused by inappropriate management or a lack of understanding about player performance and/or tactical orders.
Quality and morale etc do not give you much of an advantage when the most important management aspect of the game is ignored (keeping good performing players on the field while benching the bad).
A real troll result is that your player vastly outperformed (everyone with good rating and all), getting the tactics right (having much more chance created in the match), and still lose the game because of unlucky dice roll. Such scenario only happens like once in 50 games.
