I'd sacrifice the 4-2-3-1 for this Xmas tree:
Marchisio-Momo-Melo
Camo(Gio)-Diego(DP)
Striker
Melo can cover for Grosso when going forward.
Marchisio can cover for an RB when going forward.
Momo do the usual and cover the whole central area with the help of one of Melo or Marchisio or both if possible.
This is what I call SOLID MIDFIELD.
God, I've never thought I'd be tempted by a Xmas tree but this is really :lick: for me!
