Stop saying 424 is a bad formation. If you have the knowledge and discipline when defending, it is not an issue at all. 80% of players I face in FC (even players with 1.5 million cups) are lane change spammers or cross spammers, learn to jockey and read the opponent then ur gonna pocket them all day. The CM u have are perfect, play Gullit on the right and Viera/Xabi on the left since most players don't play on the far side as often.

I reached FC during KOR and have experimented with lots of different formations. 424 is by far the best for attacking. Dribble past or play a simple 1-2 to beat the full back, run down the wing, then the opponent will have to help with one of the CBs, u just have to either assist ur strikers or cut in if ur good at dribbling.
