How could this formation humiliated my team?

[George Campos de Oliveira]

I would try 3 Defenders (DC_DC_DC), and a MDC, to act against his attackers and AMC.
I would try 4 Middlefielders to control the center. (MR-MC-MC-ML)
2 ST
Attack in the middle. with mixed pass...Since you have nothing to do, but Victory, try attack.
But I really dont know if it works

It should, he blocks the flanks and attacks through the center.
So when you block the center and also attack through the center you should be fine.
