Manchester City boss Pep Guardiola has ruled striker Sergio Aguero out of the Manchester derby next weekend, reports BBC Sport.
The Manchester City manager previously said Aguero 'would need a miracle' to recover from a thigh injury on time to face United at the Etihad Stadium on 7 December.
At his press conference on Tuesday, Guardiola confirmed the Argentina forward would not make it.
"He won't be ready for the derby," said Guardiola. "After that we will see."
