Arsenal manager Arsene Wenger has revealed Hector Bellerin will miss the crucial Champions League tie against Bayern Munich on Wednesday night (4 November) due to a groin injury. The French boss, meanwhile, has been forced to include 17-year-old Jeff Reine-Adelaide in the squad to address gaps on the right side of the pitch, with Aaron Ramsey, Alex Oxlade-Chamberlain, Theo Walcott and Bellerin on the sidelines for the game.

The Gunners beat the Bundesliga giants 2-0 at the Emirates Stadium to revive their hopes of reaching the last 16 after their poor start in the competition, with two defeats in the first two group games against Dinamo Zagreb and Olympiakos. Nevertheless, they still have a big test ahead with them as they are currently bottom of the table, with the same points as the Croatian side but three behind both the German and the Greek teams.

Wenger has revealed Arsenal will need to face the challenge with second choice Mathieu Debuchy in the right-back role as Bellerin had been left out due to a problem in his groin.

"I have confidence and trust in [Debuchy]. Physically he should be ready," Wenger said in the press conference ahead of the game, as quoted by Sky Sports.

"We need to give a similar performance to when we played in the first game. I expect Bayern to play offensively and try to put us under pressure. We have won everywhere in Europe and we will try to win this game."

Bellerin has joined a nine-man injury list, which also includes David Ospina, Jack Wilshere, Danny Welbeck, Tomas Rosicky and captain Mikel Arteta.

Joel Campbell played against Swansea on the right side of the attack but Wenger has included Reine-Adelaide to provide competition for the Costa Rica international. Having signed during the summer transfer window from the Lens academy, the French teenager can adapt to different positions and had some impressive performances during the pre-season Emirates Cup.
