Gary Neville has questioned why Arsenal left it until transfer deadline day to try to bolster their midfield as he believes they are light in that area of the squad.
The Gunners were ultimately unsuccessful in their attempts to sign a midfielder in the final hours of the window as they had three bids rejected for Aston Villa's Douglas Luiz, the last being £25million plus add-ons.
22-year-old Fabio Vieira was signed from Porto at the start of the summer but injury prevented him from making his debut before coming on as a substitute in Arsenal's 3-1 defeat to Manchester United on Sunday.
