Excellent form - from my team in the season start!

Well, got 13 wins, and 1 draw.
I buyed many players, only 5 players in this photo are from the previous season, the others all new.
I gotta admit, my only aim now is - THE CUP. I never won it.
I use the 4-3-3 formation, but some matches in the CUP, i used the 3-5-2. If anybody got an idea to help me with those players, how to success in THE CUP, Tactics, formation etc. ;)

Tell me about yours team orders. Cup is really hard to win. I am on lvl 10 and I just won Cup once. Rest I lost in first or second round.

Hard attacking, Mixed, Whole Pitch, Normal, Mixed, Zonal
