One of my best (coming back from a 4-1 defeat in 1st semifinal against Eintracht) and worst (losing on extra time against Aston Villa when missing a penalty in the 65th minute) FM experience using 4231 BlackDog in my Domzale youth to gold/building a nation save... Using it more frequently towards end of season.
Nice result! Will try it with BK Häcken, halfway thru first season.
Do you ever start games with the DEFEND tactic? And, have you also a updated version of it?
