I add my situation also to this question.
Today I've played at home the first cup game.
Oponent played 3N-4-3.
I played 4-3N-2W-1.
The result was 0-0 so tomorrow I have to score and draw or win.
In my team I don't have MR and I have very weak AMC and only 2 striker (one of them is poor)...

This is my second season so i'm still building the team. Maybe I will buy anyone tomorrow but I cannot be sure about it on transfer market...

Can someone suggest something?
