you are comparing a decent form aquilani to an out of form marchisio, not quite fair.
aqua is critical for the team at the moment. if marchisio picks up the form from last year, he still is better allround.
aqua has the vision, passing and long shot, marchisio is superior in any other cathegory.
we should really play 4-3-2(wingers)-1 when both r in form
melo to anchor, marchisio and aqua in front, and martinez/pepe and krasic on the flank, 1 striker.
