Formation to go against 4-4-1-1?

[adifairus]

about formation:
when your opponent got AMC, you will need DMC,
you also need fullback because opponent got flanker
others doesn't really matter

about tactic;
because you said your opponent is stronger,
just play defensive mentality with ON counter attack,

and counter attack is very effective if
i) you got AMC/AML/AMR
ii) and the DMC(high creative skill) as the ignition of counter attacking

suitable formation in your case
i) 4-1-2-1-2 Narrow diamond (focus through middle)
ii) 4-5-1 V (focus passing mixed area)

(use 4 defender is suggested because your opponent is stronger)
