If you have the better team, it is.
But not all the counters work. You should look at the opp past games, and form your own oppinion.
And for f%^&%&^%k sake, change the formations/tactics, ingame, if they don't work.
If you are 20% to 30% weaker in quality, your only chance is to play counter, 4-4-2 or 4-1-2-1-2 ND.(and pray)
