3) Mesut Ozil is a No. 10
The German playmaker had a superb game against Aston Villa deployed in the centre, but was pushed back out on the wing against Tottenham to accommodate both Aaron Ramsey and Jack Wilshere.
Whether it is a mental thing or something to do with his instructions when playing out wide, Ozil just does not perform as well when he operates on the flanks.
When Arsenal’s Welshman went off injured before half time, Ozil was pushed back inside, which reinvigorated the German and we saw a much brighter player in the second half.
