If you re going to claim its "The best tactic in FM20" you really should be backing that up with more than your own save game, 5 seasons in to the portugese league with a team thats one of the strongest and plays garbage most weeks.
FWIW i have tested about 20 tactics from this forum this year and this has been one of the worst, not thee actual worst but close to it. It was so bad iv completely disregarded the run of form and went back to an old save. After 5 games and scoring 0 (i average almost 3 a game normally), conceding 7, 34% possesion at home v Norwich in cup who are a league below and falling from 1st to 3rd in the English prem i dont think its the best tbh
