The highly talented full back is in need of some regular first team football at a higher level and since that is not possible at Arsenal, the Gunners have decided to send him out on loan.
With the likes of Gibbs, Monreal and Hector Bellerin already at the club, it is highly unlikely that he will be able to break into Arsene Wenger’s plans this season. Therefore, a loan move will be beneficial for all parties involved.
Moore can come back as a better player next season and then force himself into the manager’s first team plans.
