There are 2 teams that come to mind. One I won and draw a lot of times but he still had something that made him always favorite especially every time we faced in the cup or CL finals.
The other one was a total black cat and he was kinda of a jerk always supporting the rival even when our matches where not in the same time. I wanted to beat this guy so bad but all I could get was a draw. I still denied him the league twice which made me so happy, The strange thing is he has never changed his formation and still treble after treble or at least a 3rd or a 2nd place, I don't know that is one of the reasons i believe in the predetermination of the game.
