thanx frnds for all of your real valuable conceptions ...according to my conception when it comes for "false9"..a team who starts their game with 4:3:2:1 could play with this strategy provided when they will turn with 4:3:3...an attacking miedfilder will make a constant disturbance into opositions backline(last 6 to 10yards of opponents half)

According to my understanding of a "false 9", a team who starts their game with 4:3:2:1 could play with this strategy provided when they will turn with 4:3:3. An attacking midfielder will make a constant disturbance into opposition's backline  (the last 6 to 10 yards of opponent's half).
