I dont know the game well enough tactically in this years version to be doing unemployed saves yet.
Anyone able to get fullbacks to defend? No matter what i do they are incapable of marking and tackling.
Ive tried every single player role and mindset, having ball winning midfielders helping, having an anchorman, limited defenders helping. Nothing works. Wingers always run past them or get away from them in the box to get on the end of corners.
I've only played with a fairly good team so far so probably wouldn't be able to help you much with the defending.
However, you can try to use that to your advantage too - I've found my wide players to be incredibly effective, and fullbacks from other teams were also frequently among the players with most assists in the Brazilian league.
My team was set up with 4 at the back, 1 DM, 1 CM, 2 wingers and 2 strikers (very attacking).
The fullbacks were CWB set to "attack", while the two wingers were in "support" mode, with "Look for Overlap" instruction in both sides as well as "Work the Ball into Box" (or something like that).
I encouraged my team to play through both sides. That way my four wide players were to a large extent my most important players, wingers scoring 15+ goals per year and fullbacks getting many assists.
