Bukayo Saka was forced off after just 10 minutes of Arsenal's Champions League match against Bayern Munich at the Allianz Arena, handing the Gunners a major injury scare.
Saka started the game as Mikel Arteta named his strongest available side for what was described as the toughest test of the season. The winger had wriggled away from Alphonso Davies and played a pass out wide, but immediately went down clutching his left leg and signalled to the bench.
Saka's early exit
After playing the pass under no real pressure, Saka was replaced and looked extremely uncomfortable as he hobbled off the pitch. He stopped on the touchline to speak to Arteta and appeared to signal to his left quad before continuing down the tunnel.
Eberechi Eze came on to replace Saka, with Madueke moving over to the right wing having started on the left.
Winger shortage
Arsenal are already short in wide areas, with Christos Tzolis out of action since the international break with a hamstring injury. If Saka faces a spell on the sidelines, it would leave Eze, Madueke and Max Dowman as the only fit wingers available to Arteta.
Arsenal have five matches in the next 17 days before the November international break, including a trip to Anfield to face Liverpool in ten days' time.
