Guibbling!
But, I go for "either foot" on corner takers and free kick takers, thats it.

Rules to success:

Management
Play with legal formation, use player on right position. Preorganize your subs, penalty takers, corner takers and free kick takers.

Support your team:
Waste some cash on tockens (makes mama Nordeus happy) and buy good players, remove players with red cards. heal injuries on key players only, moral boost your players and have well rested players in the pitch.

Support others (Friends)
Avoid friends on the same level, also make sure your fiends dont have friends on your level. Make your fiends support your games.

Useful skills on players: Free kick takers, corner takers (either foot)

Helpful skills on players: One on one scorer, one on one stopper, shadow striker, arial defence, defencive wall.

Useless skills on players: Penalty stopper, penalty kick specialist, dribbler, playmaker.

Oh I almost forgot, do not get greedy, you´ll never win them all! Have you ever seen a player winning all three trophies season after season? It just wont happen. Mother Nordeus share to us all.
