You said those bug players have low shooting and finishing but score was ridiculous.
GK don't have shooting, finishing, how can he score? is this ridiculous? -> glitch?
How can you know both players today didn't change tactics? => you mean formation, right?
There are something make me wondering:
I see from your yesterday post, your opponent seems quite active to change formation, how can he not change anything when he down 0-2?
Did you change your formation just before the game so he changed his right after the game began?
To clarify the theory the engine favors these type of players:
one of two bug players from your picture is 18yo, so last season he won over you with just one bug player, right?
No need entire team, why do you not try with one player?
Have you tried it yet?
