How is that the same?
Besides, does it really matter who of the 2 the better individual player is? For me, it doesn't. What I care about is what's best for the team, or in other words: putting the best possible team out there.
Which, in regards to Marchisio, inevitably leads to a very simple question: is the team better with or without Marchisio in it?
I haven't seen anything (yet?) to point me in the "without" direction. Others probably will have, going by what you tend to read on here.
How you go about fielding him or who needs to make room for him is an entirely different matter.
Obviously.
You'd think that would be the case for everyone.
