LOL I'm the only with luck using the 4-3-3 :'D well... attacking mentality, normal tackling, pressing?? own half??? try in all... and focus passing in the middle... really I've comproved that this option is very exclusive, specific, try in mixed, not for the middle, too counter atacks and offside active.
1 option is that you have more players bad programmed comparing with the other team.... that's really not normal...
and good for his players, I too won a league saving my old players of 1 star (and yeah playing with some scouts but...),,, curious, but true, all is programming by default. Train 1st speed/resistance to 9 stars.
