Hey dude! Your brother is in my squad!
Just kidding
Sorry for the interuption.![]()
I think your opponent was trying to counter your formation by placing DML and DMR to block your winger and a DMC to intercept any pass from the center. He probably use counter attack from the flank to exploit the empty spot on your wing left by the AML and AMR because the 2 of them are too far to help the wingbacks to cover your opponent's wingers. And he proved to succeeded to counter your formation.
As for the formation I suggest for you to play 3W-5-2 or 3W-1-4-2 defensive and counter attack from flank. The idea behind attacking from the flanks is because mathematically there are 5 players in the center area (1 MCs, 1 DMC and 3 DCs) which is a very tight defense. While on the flank he only have 2 marker, which are the wingbacks and an extra DC that is close to the wing back to provide extra cover. The defensive mentality makes your opponent's player come forward to attack you and it makes the gap between each player farther thus makes it easier to get pass by your winger.
That's my 2 cent bro.
