Sometimes you need to be offensive as well as defensive and make important decisions on how the games are going, 4-4-2 is fine, I play 4-4-2 normally myself, its not an attacking formation, but quite a difficult formation for other managers to predict because they don't know if the attack is coming from the middle or the flanks, but of course you need a Plan B if its not working, I have switched to 4-1-4-1 or 3-5-2 on a number of occasions when I feel its needed. I even started a game 4-3-3 against a Level 16 team when I was Level 13 in the cup because I knew I had to score goals and I switched to 3-4-3 near the end of the game to get an 89th minute winner that took me through on away goals. Sometimes you have to set yourself up a certain way when facing an opponent.
