PHOTOS: Gallery of Diaby back in action for Arsenal under-21s against Chelsea

Long time injured Arsenal star Abou Diaby made his comeback for the Gunners last night.

A sight Arsenal fans feared they may never see again, Abou Diaby donned the famous red and white shirt at the Emirates last night.

While it was only and under-21 game in front of 1,300 spectators, his appearance was still a major step for the central midfielder.

Diaby suffered a torn ACL in mid-March 2013, and his slow rehabilitation meant it more than a year passed until he returned to training.

The Frenchman has not given up on a World Cup place, and Arsene Wenger did not hold back in throwing him into action, and he seemingly passed the first test.

Diaby played the first 45 minutes against Chelsea last night, with the club 1-0 up thanks to a Hector Bellerin goal when he was substituted.

Two second half goals from Lewis Baker and John Swift ensured a 2-1 win for Chelsea, with Arsenal's website noting: "The Frenchman looked tidy in the early stages of the game before fading towards the end of the first half."

Diaby is clearly a long way off full fitness, and it's unrealistic to expect him to play any meaningful role this season at Arsenal.

If he can continue his rehabilitation process, and there's an under-21 game this Friday against Newcastle, he may put himself in line for a cameo appearance in the FA Cup Final should Arsenal be in a winning position.

The real challenge for Diaby is to show Arsenal that he is deserving of a new contract. His current deal is set to expire, and while a move elsewhere with a fresh start and better chance of playing regular football may be beneficial to him, if Arsene Wenger believes in him as much as he suggests, Diaby simply has to focus on staying fit.
