Pep Guardiola fears Manchester City's injury list could could prove their undoing this season.
The Premier League champions have had a number of fitness problems already this season with Rodri and Oleksandr Zinchenko becoming the latest casualties this week.
Midfielder Rodri is likely to be out for a month with a hamstring injury sustained in Tuesday's Champions League defeat of Atalanta. Left-back Zinchenko is facing up to six weeks on the sidelines after undergoing minor knee surgery.
He said: "I would prefer all the players had no injuries but I have to do it. We can't stop and complain, 'Oh what bad luck'.
"We have good players in the squad. In a few positions there are not many but we have incredibly good players. We're going with them."
