Arsenal keeper Matt Macey has signed a contract extension to keep him at the club until 2018.

The 21-year-old moved to the Emirates from Bristol Rovers in 2013, and has been an unused substitute on 15 occasions this season.

Petr Cech and David Ospina remain manager Arsene Wenger's preferred first and second-choice options, with Macey continuing to play for the U21s.
