i am much more eager to see Marchisio involved in our first team, than Del Piero...Especially given the current form of Diego and Camo, and to a lesser degree, Giovinco.
the 4-3-1-2 looked poor when we lacked match sharpness...and ALSO...when Ciro was playing two target men in attack. Yes, with DP back in contention we could revert to a double act of target man and flair merchant. DP and Amuri/Trez...also, this would allow Marchisio to slot in beside Momo and Melo...but at the expense of Giovinco AND Camo???
I would prefer Marchisio to challenge momo and melo, and also cover the attacking midfield positions, where he may not be as creative as the first choices, but he is certainly more effective, at least in the flank positions, than De Ceglie or Tiago. Perhaps he is also more useful than Tiago in Diego's position...that is an unknown. And I doubt we will learn the truth of that matter unless Diego gets mauled.
So...Marchisio's chances of first team inclusion are directly tied to DP's chances, when everyone is fit and firing on all cylinders. In the current 4-2-3-1 formation...he will have to settle, most likely, for back up to Melo and Momo, though they pick up plenty of yellows, so he won't have to wait very long to stake his own claim.
