2) Buy defenders
Everyone with even a vague interest in football looked at the six Arsenal defenders had at the start of the year, following the surprising decision to get rid of Thomas Vermaelen and Carl Jenkinson, and said “they haven’t got enough defenders”, and so it has proved. Injuries to Mathieu Debuchy and Laurent Koscielny have meant that Nacho Monreal has been playing at centre-back for the last two games. It doesn’t particularly matter who the Gunners buy in January, they just need depth.
