I know how you feel Herbie, however I'm quite the opposite, my teams are deservedly losing because I haven't got the tactics right...I've decided to stop studying players and just throw any tactics out now, and see how trying to be "Unpredictable" goes for me...If I get relegated, I get relegated, but may as well try something new since nothing seems to be working for me.
I've been trying to see if the 4-2-4 formation works, to try and counter this 2-5-3 system people use, but I've not had a game yet to beat the tactics with someone playing 2-5-3 yet to see if it works or not, since not many people use this system it's hard to test, and I really need the game to be in long-ball conditions to optimise 4-2-4.
