I don't think i ever lost against 4-3-3
I'm only at league 6 but i have won this...
league 4 times
Runner up 1 time
CL 2 times
CL final 2 times
Cup 1 time
cup final 3 times
So i believe i know how to win but it gets very hard to win when the core of your team, 5-6 players that have proven to be very good player for the last 2-3 seasons, one of them even from season 1 all the sudden perform 4 and 5 rating in every game instead of the avg 8 they have always done.
Only way to fix that is to buy a lot of tokens and buy a new team and i think that is the reason they perform so bad, Nordeus is trying to force me to pay up.
