Only Nicolas Otamendi is fit with John Stones ruled out because of a muscle injury and Aymeric Laporte (knee) also sidelined until the new year.
Fernandinho is expected to fill the void and manager Pep Guardiola says the central midfielder "can deal with it".
"He will do well because my players are well," he said.
"We will create something, it is what it is."
