Arsenal's Champions League hopes have been handed a major boost after Bayern Munich winger Arjen Robben was ruled out of the must-win game with a thigh injury. Robben has been out for the last six weeks since suffering the injury during Netherlands's 2016 European Championship qualifier against Iceland and has not traveled for the Bundesliga champions' third group match.

"Arjen Robben is close to a comeback but is not yet match fit," a statement read, after Robben had stated he was in "perfect condition" for the game. Milos Pantovic has also not made the trip to London, the club have confirmed.

Striker Robert Lewandowski has travelled however, despite picking up a knock in the win over Werder Bremen. The 27-year-old has already scored 16 goals this season for Bayern, including three in Europe's elite club competition, but is expected to be fit for the game. Kingsley Coman is also fit along with reserve goalkeeper Ivan Lucic.

"I'm feeling very good," Lewandowski told the official Bayern website. "Arsenal are under pressure, but they're always dangerous at home."

Bayern have enjoyed a perfect start to the season, winning all nine of their Bundesliga games to top the table. The German champions have also won both of their games in Group F, overcoming Olympiacos and Dynamo Zagreb in their opening two games.

Pep Guardiola's side are unbeaten in two of their three visits to The Emirates Stadium, beating the 10-man Gunners 2-0 in the first leg of the last 16 first leg tie between the two sides during the 2013-14 season thanks to goals from Toni Kroos and Thomas Muller. Arsenal have twice perished in the competition after defeats to the Bavarian giants.

Arsenal's Champions League hopes hang by a knife-edge after defeats in their opening two group games. Just nine of the previous 110 teams to lose their opening two games have subsequently qualified from the group stage, meaning the club face an uphill task to reach the last 16.
