Jamie Redknapp has highlighted one transfer that Arsenal are being made to rue this season.
The Gunners are enjoying a fine campaign but after Saturday's 1-0 defeat to Aston Villa, they now sit second after Liverpool beat Crystal Palace earlier in the day.
John McGinn's seventh-minute strike was enough for Unai Emery's side at Villa Park as they won their 15th home league game in a row, although Arsenal thought they had equalised before Kai Havertz's last minute goal was disallowed for handball.
