4-5-1 V Which is the correct use ????

[dimdim1]

do you use counter attack/offside trap?

NOPE TO BOTH.

be careful with of side trap...if the opponent has AMR-L never use of side trap.
Counter attack i have used 1-2 times (against very stronger 4-4-2) CL final last year which i lost ,but i had set defensive mentality.
I never use it dont know if it works.
