People, you can't purport the excuse that Marchisio is tied to a system and therefore can only do well tactically. That is nonsense.
Why? Well, what position does he play? Is he a playmaker? No, he's not. He's a central midfielder. It is his job to be tactically adept and make short passes with ease. So what's the difference between him being in a certain system as opposed to having a "freer" role? Absolutely nothing.
Just give it up, guys. Marchisio is a great squad player, a water-carrier, but that's it. If you think he's going to be a our Steven Gerrard you are completely delusional.
