Arsenal teenager Gedion Zelalem will not make his competitive debut for the club in Tuesday's encounter with Chelsea in the Capital One Cup, as he is still not up to speed following a knee injury.

The 16-year-old tweeted last week to confirm that he was training with the first-team squad, which appeared to suggest he may be afforded the opportunity to play against Chelsea this week.

Zelalem, though, will not be granted his senior Arsenal bow due to a knee complaint he has endured which, says Arsene Wenger, means the player will continue playing for the under-18s, rather than the first-team.

"He is not yet available. He had a knee problem," Wenger told Arsenal Player.

"He is back in full training but he has not played yet. He will play 45 minutes with the under-18 team later this week."

Zelalem is regarded as one of the most exciting young talents in the Arsenal academy, and the German impressed immensely with his performances for the club during pre-season.

The midfielder was particularly eye-catching in the friendly defeat of Manchester City in August, and it would appear to be only a matter of time until Arsene Wenger utilises him again.
