I think Sunday should be for the Brazilians and Schurrle to get playing time for match fitness. Tuesday should be the squad we will field against Burnley.
I don't think it's a minor possibility. Every player can miss a pass. A 4-3-3 works best with the guys we have now is the main draw. It seems we are using a formation for a squad we don't have any more.
The difference is if he makes the error at the 10 there are two guys behind him, plus someone like Willian next to him with the speed the run the length of the pitch, to close it down. That is much different than when you are already further back.
