Arsenal are lining up Toulouse youngster Serge Aurier as a possible replacement for Bacary Sagna. Sagna could leave the Gunners this summer as his contract expires in June and he is yet to agree a new deal. The former Auxerre man is reportedly being pursued by Inter Milan. Wenger is currently exploring full-back options in case the experienced Frenchman moves on, and he has now set his sights on Aurier.
