your formation doesn't have balance
I can see a void in the middle field (you are too strong in the wings) and a void between attack and defense (too vulnerable in counter attacks).
Probably he striked back with counters.
To tell you the truth, I 'm surprised you get to the semis with this formation.
Probably you did other things right
ok
MR+AMR and ML-AML is a bad combination.
I suggest 3DC-1DMC-ML-2MC-MR-AMC-ST
def/counters/mix
norm/norm/zone/of
If doesn't work, then use your orders above
good luck
