This tactic seems to be game breaking and I love it! Playing Colón de Santa Fe in Argentina's lower league and all three teams (First, Reserve and U20) can't loose. Haven't been FM'd yet, so I will update after the season is over, but so far so good.

The only downside is that I have a lot of expensive strikers that are now riding the bench! I am retraining to play AMC.

Thanks for your work on this!
