Wouldn't be massively surprised, Wenger has been talking about how he's lacking in confidence
Although conversely the problem there in lies if Ox plays higher up who would you play behind him
Frankly if it were me, i'd think sod this and play Elneny and Maitland Niles there.....and then play Welbeck, Sanchez and Perez up top
Ospina, Bellerin, Koscielny, Mustafi, Gibbs, Elneny, Maitland Niles, Ox, Welbeck, Sanchez, Perez
