Hi

Last day i forgot to follow a cup match and lost due to unluck(my top midfielder got backache after 6 minutes... and there's no auto-substitution). I now need to win 2-0 the return. It shouldn't be a big issue since my team is much stronger than his, but anyway i would like to know an affordable tactic against his 4-3-2-1(aml-amr) to be sure not to fail.
In the previous match i lined up a 4-5-1 with up arrows mr-ml, offensive style, high pressing and offside trap. Since my top midfielder is now out and i don't have a good one to substitute him with, I was thinking about a 4-men midfield like this:
GK
DR(UP)-DC-DC-DL(UP)
MR-MC-MC-ML(UP)
ST(DOWN)-ST(UP)

to exploit the opponent's lack of potential in his right hand side and limit his strong aml. What do you think about that? What tactic should i use?
