Hello everyone. Everything was great then i had old pc and were using might and magic by raikan tactic. About two weeks ago, i got new laptop and installed manager with 12.0.4 patch and Summer transfer updates. Might and magic doesn't work, losing to sunderland with Chelsea 1:3, tested another tactics (like MAN UD in 12.0.4 patch, unbeateable tactic by hazaraa, two of xenons tactics), neither worked for me... Is there is tactic which sould work for big teams in patch 12.0.4 with summer transfer updates? 
Thanks for answering!
