Tonight i'll have an vital cup-match against a strong team using 4-2-2(AML/R)-2. This is the first time i handle with this formation. i just search all the threads about countering formation and some pointed out that 4-5-1(V) and 4-1-2-1-2 narrow diamond are the best options. Luckily my squad can change both of them easily but i still dont know to choose what the starting formation to counter him and what should i use the tactics and arrows in both formations, and what is the best one to counter the Hexagon

notice that its an away match. Hmh.. any ideas or experiences? i would appreciate!
