I am also seeming to have problems right out of no where. Dominated my first season with AC Milan, 1 loss all season, finished with well over 100 points, never seemed to get the massive 6/7/8 goal wins you see in this thread, but we would always win. Had a massive clear out and bought players who actually fit the tactic thinking it would be even more effective, and at first that seemed to be the case, starting the season not conceding in the first five games, with some convincing wins such as a 5-0 away win over Roma. However, since the most recent update, I've got on a string of 5 1-0 losses, I understand that losses do happen but its the nature of the losses, the tactic seems to be completely broken, I play on extended highlights and in some of the games I don't even get one attacking highlight at all, there's just one all game and thats the other teams goal? Strange how such a small update can change how a tactic works.
I was using the original tactic by the way with Jesaustralia OI
