Manchester City have been dealt a key blow ahead of Sunday's clash with Chelsea after an injury suffered by John Stones that looks set to keep him sidelined for "a while".
The versatile England international started for Pep Guardiola's holders against Young Boys BSC in the Champions League on Tuesday night, but was replaced by Nathan Ake at half-time of a one-sided 3-0 victory in Group G that saw the dominant holders qualify for the last 16 of Europe's elite club competition for the 11th successive season with two matches to spare as they also set a new English record by extending their long unbeaten run on the continent.
