Hey,
I trief a new formation in the last two matches but i lost both and i have no idea why.

My formation:
ST
AML-MC-MC-AMR
DMC
DL-DC-DC-DR
GK

4/5 star players

Mentality: attacking
Passing: both flanks
Pressing: whole pitch
Offside trap [x]

The rest is standard setting

My opponentd had a 3-4-3 formation

Any suggestions? What should i change?

Thanks for the help
