A position of weakness for Arsenal so far this season has been on the left-side of the defence.
With Sead Kolasinac and Nacho Monreal struggling for fitness and form, Unai Emery has had a number of tough calls to make throughout the campaign.
Granit Xhaka has even had to fill in at left-back on a number of occasions, with Stephan Lichtsteiner also having been utilised.
If Arsenal were to sign a new left-back in January, who should they go for? Here are some suggestions…
Alex Telles
Telles is highly-rated in Portugal and could make the step up to the Premier League. He has had plenty of Champions League and Europa League experience to date.
Ryan Bertrand
With Southampton struggling near the bottom of the table, this could be the perfect time for Arsenal to swoop in and secure a deal for Bertrand. The England international has been one of their more impressive players in recent years.
Jonas Hector
The German international currently playing in the 2. Bundesliga. Hector could be convinced to return to top-flight football and try his luck in England.
Ben Chilwell
Despite recently signing a new deal with Leicester, a large offer from Arsenal could make this move a possibility.
