Mathieu Debuchy
The Frenchman looked like a great signing at the start of his Gunners career before suffering a terrible injury after only a few appearances. Gooners were concerned with Carl Jenkinson on loan at West Ham and our only right back the untested Hector Bellerin. But the Spaniard has gone strength to strength under Wenger and has moulded in to one of the most promising right backs in Europe.
Bellerin has well and truly cemented his place as first choice right-back and after a lack of games this season Debuchy has been vocal in his frustration, hinting on several occasions that he will look to force a move to make the French Euro 2016 squad.
He’s featured in some of our worst performances this season and has upset fans with his lacklustre showings and attitude in the opportunities he’s been given. With him entering his peak and with plenty of Premier League experience we could recoup a few million for him and replace him quite easily.
