I must score 3 goals against a 4-3-1-2 wide...help pls..

[gkassimis]

your plan B can replace DMC and put a striker. I play on tactic that gkassimis suggested and when the team not scores, i put another striker. you can also change the formation to 4-2-4 :
PL PL
AML AMR
MC MC
DL DC DC DR
GK

and in which case you can choose to attack the flanks

without the dmc the opponents amc can destroy you. it's risky.
