Manchester City boss Manuel Pellegrini was delighted with two-goal Sergio Aguero after victory at Stoke City.
Aguero's goals indicated a return to form in his sixth game since returning from a knee injury, although he was later withdrawn as a precaution due to a back problem.
Pellegrini said: "When Sergio has more minutes he will return to his normal level of performance.
"He felt something in the back. My feeling is it is not too serious and he now has 10 days to recover and train well. I hope he will be fit to face Newcastle."
