Laca dropped, Auba starting, Iwobi playing, Wilshere on the bench as well.... it will take time to see what happens but, you'd think if he intended for Auba to start wide left consistently he would probably do that straight away.
If we bought Auba to just replace Laca, I think he's better for sure but Lacazette's biggest issue has been lack of chances due to the way we play and lack of giving him the ball, Auba would have the same issue. It's Ozil at times, Iwobi, Ramsey, Xhaka who have been not finding the striker and where we needed improvement.
Surely we have to just play Laca wide and hope he can play there, can he honestly be worse than Iwobi who has been an utter joke?
Even just on a confidence level, dropping LAcazette right after buying Auba certainly sends the signal that you're done.
