City take on Chelsea at the Etihad on Saturday evening and manager Guardiola has revealed the state of play with absentees. The former Barcelona boss said Grealish, who went off against FC Copenhagen in midweek due to a foot injury, was unavailable, and Silva, who was taken off in the second half with a knock, will have a late fitness test. The ex-Bayern Munich manager added that Mateo Kovacic and Sergio Gomez are back training, while Gvardiol is not ready to return.
