What i mean it's that your first result, let's say away, could have an influence on how you gonna prepare for the next game (home).

Off topic. Remember this. One single formation, in your case, 4-1-2-1-2 ND, it's not enough. You gonna play against loads of different tactics/formations and every formation have a counterformation. So, my advice, and probably many others will tell you the same thing, try to have players with 2-3 positions on the pitch, so you can switch and use a different formation for every player you meet.
I am used to switch between 4-1-2-1-2, 4-5-1V, 4-2-2-2 and 2-3 more, so i have DL,DC,DR,DMC,MC,AMR,AMC,AML,ST. Almost everything except MR, ML,DML,DMR. If u'll use ND against any opponent, u'll lose more games then u expect.
