It's not a troll.
There are some factors that affect the result of the game, but this isn't standard.
I believe that there is a separate roll dice
Some times it seems that condition and morale are important (or not)
some times presence of the manager is important (or not) - yes in your case
some times formation is important (or not) yes in your case, your 3 attackers won oppo 2 DC.
and 1/2, 1, or 1 1/2 star quality doesn't make a difference.
