The Argentine striker returned from a knee injury to play 15 minutes of the Manchester derby on Saturday but was the victim of a heavy challenge from Ashley Young late in the game.
But he looked fit and healthy as the City players trained at the CFA under the watchful eye of Pep Guardiola.
Benjamin Mendy was also present as he continues his recovery from the anterior cruciate ligament injury he suffered in September, but both John Stones and Danilo sat the session out.
Earlier on Monday, Guardiola revealed Stones has been struggling with an adductor muscle problem, which is why he missed the derby on Saturday.

“In the last game, he had concussion with the national team, he could not play at Everton and did not train,” Guardiola said.
“And then before United again he felt something in his adductor and it was not perfect, so I decided not to take a risk.
“He knows the confidence I have in him, this season he grew up. He has to fight with these guys to convince me [he should play].”
