I use 4-1-4-1, reds n ML/MR defending/hard defending with counter.
But if the other team scores,or he has more shots/opportunities, i change to 4-5-1 V Style.
And i make multiple changes uring the game, if it's not going well for me.
I move players around, MC's between them, ST's between them.
I change the tactic to attacking, if they score.
if i don't get counters, i uncheck the counter, and usualy i get a few counter after that.
