From what little I saw (at work) it seemed Basel was playing alright but we were just too much for them.
Ozil may need to start drifting wider to find more impactful play as Sanchez is, and has the stamina, to play as a CF who leads the line and drops deep (into "Ozil territory").
Though I will say, without Theo on this type of form I wonder what we would be saying about Sanchez at CF.
