Arsenal manager Arsene Wenger has confirmed that Hector Bellerin will miss tomorrow night's Champions League match against Bayern Munich with a groin injury.
The 20-year-old right-back was impressive in the Gunners' 3-0 victory over Swansea City, but he will play no part in Wednesday's match at the Allianz Arena.
In today's pre-match press conference, Wenger said that the groin injury was just a "small problem", indicating that the full-back will not be out of action for a lengthy amount of time.
Mathieu Debuchy is expected to take Bellerin's place against Bayern, who were on the end of a 2-0 defeat to Arsenal at the Emirates a fortnight ago.
