Mesut Ozil has just turned 29. For some footballers, that mark can represent the end of their peak years, and there's also a strong case that Ozil is hurtling towards the end of his time with Arsenal.
His current contract expires at the end of this season, and while the Gunners are still outwardly optimistic about the possibility of an extension, Arsene Wenger has admitted to the Guardian that Ozil could be sold in the forthcoming January transfer window.
The possibility of Ozil leaving the club inevitably prompts discussion of his legacy.
