Try this.
Belletti---Puyol---Edmilson---Gio
Marquez
Xavi-------------Deco
Giuly------------------------Ronaldinho
Eto'o
I like substituting Maxi for Giuly at half time and switch him with Eto'o. The cameroonian gives me good results as a winger, and Maxi is strong and mighty in the air.
But i still find all these formations (including mine of course) are useless unless you improve the stats. Their default settings are complete and utter bollocks. You should improve Deco and Xavi's passing and dribbling skills. Give most of the team 1-2 passing abilities as well. Improve Eto'o considerably as well. His default abilities do not do the man justice.
JmZ...WOW. You know you got some of the player's numbers wrong, right?
