Danny Welbeck was pictured back in training as he continues his recovery from a hamstring strain ahead of the north London derby.
With Olivier Giroud a doubt Welbeck, 26, could be in line for a return at the Emirates on Saturday. He was amongst several first team stars not on international duty who trained on Tuesday at the Arsenal's London Colney base.
Prior to limping out of the Gunners' 2-1 defeat at Watford on 14 October Welbeck had started six of Arsenal's eight Premier League games. The hamstring problem picked up at Vicarage Road has kept him out of action since and ensured that Gareth Southgate could not call on his services for England's internationals against Germany and Brazil.
