Seriously? Need opinions on this kind of result

[Isaac Phua]

Guys, i need your opinions on this. In my cup match, i faced against a team with lower average quality than mine. But yet, here's the result.

All my players are 80% condition and above, full or near full morale. Attacking mentality, short passing, offside trap, full pitch pressing. I got full 15% possession in my spectator tab and still, I lost?
