Manchester City were still waiting for a confirmed diagnosis on Jack Grealish's muscle injury on the eve of their clash with Chelsea - because a machine was broken in the medical department.
Pep Guardiola confirmed that Grealish will miss the visit of Chelsea after picking up a muscle injury at Copenhagen this week, but City did not know how long he will be out due to delays in assessing the state of the problem.
A broken machine meant that Guardiola was unaware of Grealish's expected time on the sidelines, adding that he would find out on Friday.
The manager also confirmed that Bernardo Silva, Mateo Kovacic and Sergio Gomez would be assessed on Friday, with Josko Gvardiol definitely ruled out.
