Thats not 5-3-2, it's 3n-2w-3n-2.
It's weak on the sides.
The point is to be good defending.
And if you score, it's good, if you don't, you go to penaltyes.
Yes, when your attacking your formation is 4-5-1 V, but when your defending is 4-1-4-1.
This meens that you have 4 defending on the side, and 5 defending in the middle(DMC).
And if you go to pen's, you will win, because this game sucks

I lost last seasons final, to a weaker team

)(5-4 penaltyes)
