Alex spent six years with us, making 199 appearances and scoring 20 goals. He helped us to three Emirates FA Cup victories, putting in a man-of-the-match performance in our semi-final win against Manchester City last season.
A year after his arrival from Southampton, 'The Ox' featured for England at Euro 2012 aged just 18. He currently has 27 senior caps for the Three Lions.
We'd like to thank Alex for his contribution to the club and wish him well for the future.
