Aymeric Laporte was part of a 23-man group that trained ahead of Manchester City's match with Dortmund.
Laporte, 28, has not featured at all this season after playing through the pain barrier in the final few games of the last campaign and then undergoing knee surgery in May. Pep Guardiola has said previously he does not expect the player to be match-fit until after the international break, but the Spaniard took part in Tuesday's session as he moves closer to a first-team return.
John Stones was also there after missing the Sevilla match with a slight injury, while there appeared to be no issues picked up from the Champions League match last week. The only notable absentee was Kyle Walker, who limped off in the 1-1 draw with Aston Villa and may not be fit again until after the international break.
