Defender Hector Bellerin has been drafted into Arsenal's starting lineup for their Champions League encounter with Borussia Dortmund.

The 19-year-old, who has played just 26 minutes of first-team football for the Gunners, is included with Mathieu Debuchy out with an ankle injury and Calum Chambers struggling with a bout of tonsillitis.

Arsene Wenger has given a second start to Danny Welbeck, despite the striker suffering with cramp at the weekend, while Mikel Arteta returns to the first XI in place of Mathieu Flamini.

Dortmund boss Jurgen Klopp recalls strike duo Pierre-Emerick Aubameyang and Ciro Immobile to his starting lineup after both began on the bench at the weekend.

However, there's no place for midfielder Shinji Kagawa, who recently returned to Dortmund after a disappointing spell with Manchester United.

ARSENAL XI: Szczesny, Bellerin, Koscielny, Mertesacker, Gibbs, Arteta, Wilshere, Ramsey, Alexis, Ozil, Welbeck
Subs: Ospina, Chambers, Rosicky, Oxlade-Chamberlain, Cazorla, Campbell, Podolski

BORUSSIA DORTMUND XI: Weidenfeller, Durm, Sokratis, Subotic, Schmelzer, Bender, Kehl, Großkreutz, Aubameyang, Mkhitaryan, Immobile
Subs: Langerak, Bandowski, Ginter, Jojic, Amini, Kagawa, Ramos
