The 30-year-old was rested by Pep Guardiola for last Saturday’s visit of Bournemouth because of muscle fatigue. After taking a full part in training with the first-team squad on Sunday Agüero suffered the muscle injury during Monday’s session.

He will have tests to determine whether he can play against Chelsea. It is thought the injury may sideline him for a maximum of two weeks. The Argentinian, who has 10 goals in 16 City appearances this term, missed last season’s corresponding fixture with Chelsea, which Guardiola’s side won 1-0.
