Out: Joel Campbell
Despite some impressive performances at the World Cup for Costa Rica, as well as in the Emirates Cup last weekend, promising youngster Joel Campbell could be on his way out of Arsenal having never played a competitive game for the club as he becomes a top target for AC Milan. The 22-year-old is understandably keen to play regularly after being loaned out by the Gunners for the last three seasons, and Wenger may struggle to fit Campbell into his side at present, making him an obvious candidate for the exit door.
