i dont believe it mate ! you would get sacked probably at half of that run of defeats!
The only reason I wasn't sacked is beacuse I took FSV Frankfurt from the 4th league to winning the champions league 3 times already and becoming the best team in the world until the last update. If not the constant success, I'd be sacked a long time ago.
Had a test run with 3 different tactics, 20 games each since the update, same **** every time - scoring almost none, conceding even at home games against bottom table teams. Even had a game in which I had almost 40 shots, half of them on target and scored a total 0. Strikers had 5.9-6.1 ratings.
Since I had the urge to smash the pc on the wall after the update's results, I stopped playing. At least until there's a normal version of the game or TFF will somehow restore his insane tactics for the new version.
