For now I haven't really seen him dropped, so it's just an assumption others would be preferred if,
say, Ox is back. Last time he was around I think nothing in the world would have dispatched Santi.
Ozil wasn't even in the neighborhood.
Now that Oz seems to be getting there, and signs of him and Sanchez working together are there,
this may present such an option. But I wouldn't be surprised if Ox was a Sanchez sub primarily, or used
in off Oz days. Ramsey's also in the equation: when Oz is AM and Santi's out, you need a very restrained Ramsey there.
Santi offers much stability, and in many ways did a type of Arteta for us.
It won't be easy dropping Santi, though if all in form it's a possibility.
