It doesn 't fit all tactics, but with Beowulf by Knap you 'll practically stop losing, I don 't know if you can beat with amateur club Chelsea or Liverpool, but you 'll get realistic results and good overachieving. It 's not even quite cheating, you just reduce the level of difficult a little bit. Worked only with Beowulf 4-4-2 20.4.1 by Knap, I 'm not sure about the other tactics.
