Skidz talks sense. 3 GK's is ridiculous overkill and a waste of Squad spaces. Your formation may be working fine now but sooner or later nordeus will tweak the game engine and and you'll need a back up plan. your squad needs a bit more variety and defensive cover. Even with 3 in attack you really dont need 5 strikers. I always try have to 2 players for every position on the pitch in my squad.
