I use counter formations and have been having trouble with 4-4-2 recently, I got a 0-0 using 4-5-1v and then changed to butterfly and lost 2-1 and I have since gone back to 4-5-1v and won 3-0 although they did have a player sent off, remember these counter formations are not 100% to work but they are known to be successful, you try them with a risk.
