Hi guys.I just wanna say that I don't really know if these counter formations actually work.I'm currently at level 8 but from season 1 till level 6 I was changing my formation before each match and nothing I managed to win and was knocked out of the champions league and cup in the early stages.At the beginning of the season 7 I change my tactic and started to play with one formation 4-5-1 V style(with few arrows and my own orders)and has not lost any match in the league,won the Champions League for the first time and conceded only 2 goals in CL and 10 in the league all season.Now,in the middle of the season 8 I'm first in the league(7-3-0 22-6),first in the Champions League group H(4-1-0 23-1)and won 4-1 the first leg of the Cup round of 16 against better team.So in my opinion, if you choose the proper formation to the players that you have in your team change of tactics will not be needed.I wish you all good luck and many trophies!
