Man you are on something...In real life scaring the **** out of players is the best method there is...If someone is scared,he is a gonner...If from the first minute you tackle them hard you have silence for 90 minutes...That guy is in shock...trauma..So I wouldn't take lightly your approach...You can use your tactic better by reading the Referee personality and use it to your advantage...If any manager has aggressive players at his disposal,he should carefully employ their unique attribute to his advantage...Football Manager acknowledge that by hiding the dirtiness attribute of each player the same way players in real life hide their dirtiness...Many players are not sportive at all but just poor loosers...
