Arsenal have signed two defenders this summer in Sokratis Papastathopoulos and Stephan Lichtsteiner so far this transfer window. 

The club have quickly resolved multiple areas but could still be in the market to buy more players if they identify the right targets.

At the moment, Arsenal have five centre-backs to play. However, with Mustafi's career at the club uncertain and Laurent Koscielny coming back from a long-term injury, Arsenal could well benefit from signing a young promising defender who could become the Frenchman's long-term replacement.

A defender who fits the bill and whom also made his impressive senior league debut against the club is Reece Oxford, who according to Sky Sports has been put up for sale by West Ham, who thus are looking for offers of around £10 million.

The tall defender who can also play in midfield has struggled to cement a place the West Ham's first-team since he made his Premier League debut against Arsenal three years ago. While Oxford excelled in the match, since then his progression at the club has faltered massively.

Oxford has spent loans spells at Reading and Borussia Monchengladbach and impressed at the latter. Despite that, he has still been unable to get close to the first-team and a move seems the best option for all parties concerned.

In Arsenal's case, they'd be getting a defender who is good with the ball and who's potential is massive. With Laurent Koscielny starting to break down as he goes through the backend of his career, Arsenal could get their hands on a cheap but high reward transfer.
