well...i use this formation since LV2... and now i am in LV7... i won all the league & CL title in 3,4,5,6 + one CUP in LV 4....well...i gave up CUP because my team is always the top Q and i won't lower my team at the end of the season...so, CUP i am always facing at least 2 LV above me....(now LV7, i have 12pts clear on the top after round 17~ and CL first leg won 2:1...mostly going into 1/4...)
i have that formation in LV2 because my defender were all injury -,- the only way i can do were 3 DC-.- (before i use 4-1-2-2-1, V shape) so, i took out one defender and put in a AMC~ so far for my team, not bad at all...only have some problem deal with 4-4-2 classic.... -.-
