No offense my friend, as I explain before, no one answer with a show-case like Beckstar did.
I search the forum but I didn't find anything in older threads.
I found an old thread about a team that won 8-9 trebles in a row. I saw comments that congratulate him but didn't read any comments that maybe this was fake or this guy was spending 400 T every season to do this.
Finally I found that in many things there are "grey zones" even from exp. managers, like
affection of win bonus, use of right/left foot, some special abilities, arrows, offside trap and last week about an illegal formation of 4-3w-3 etc.
