The whole game is just cosmetic, it is almost a .gif
Height and weight do not count, SA are a complete mystery, counter formations are not a guarantee win (you probably would have won anyway using other formations), strategy and tactics do not count (I score more goals playing defensive and man to man makes no difference?), the live animation are just premade and do not reflect your decisions or what is really happening, match stats are just made up, quality is not necessary to beat an opponent, condition and morale are the same (lose when superb, win when you are low on both).
It is just a mix of numbers and calculations that we will never know. Trying to find a reason to a defeat has become surreal, I've faced opponents on absolutely perfect conditions and tactics only to lose badly, while I won against stronger opponents just by lining up randomly.

I believe you have found your way for a perfect winning team, but probably you would have won in other ways, while losing using the same.
