2) Isaac Hayden
Due to Arsenal’s lack of defensive depth, Hayden was looking increasingly likely to see first team action for the Gunners this season. With Calum Chambers pushed out onto the right following Mathieu Debuchy’s injury, Hayden was presumably in line to fill in for Laurent Koscielny alongside Per Mertesacker.
An untimely injury has seen him ruled out until December however, with the 19-year-old missing his chance of senior football for the moment after just two previous appearances for the club.
