your team has no defensive mids (they are crucial in fifa i find), i have also switched formation this year, (i dont own the game, my bro does on xbox, i play it rarely).
you should try out a 4-2-3-1
with your left back and right back aim for pace first then defence (make sure pace is at least 85).
with your CB's aim for defence first then pace (make sure pace is above 70).
with the CDM's you aim for pace and defence (both at least 80). left footer on the right and right footer on the left (they pass better this way, trust me).
with the 2 CAM's try and get at least 85 pace, left footer on the left, right footer on the right, pace is all that matters.
with the CF you want to get the guy with the highest passing (he will be playing your balls to the striker and CAM's, but his pace shooting and heading stats should be at least 78 as well.
the striker you need a decent target man, if you prefer a pace man, get a pace man, if you prefer strength get someone like drogba/ibra, this guy should be very good and well rounded.
