Two goals from Theo Walcott and a second-half strike from Mesut Ozil handed the north London side the three points in the Premier League to make it six wins in a row in the top flight for Arsene Wenger’s men and move them up to second in the table.
Arsenal’s task was made all the more difficult after Granit Xhaka was sent off in the second half to force an uphill battle for Wenger’s side.
However, the north Londoners held on to continue their strong start to the new Premier League season.
Mustafi posted the picture above on his personal Instagram account and wrote: “🔙🔛🔝 We continue our winning streak 💪🏽⚽💥 … but it was a hard fight until the very end! #AFCvSCFC #SixInARow #Gunners #PremierLeague @arsenal”
Mustafi will be hoping to feature when Arsenal return to Champions League action on Wednesday night with a home clash against Ludogorets.
