Manchester City captain Vincent Kompany faces another month on the sidelines after Manuel Pellegrini confirmed the central defender has suffered a new calf injury setback.
Kompany returned from injury as a substitute on Boxing Day but lasted only nine minutes before limping off again, and scans have revealed he has aggravated the same calf but with a different problem.
The Belgium international, 29, missed the goalless draw against Leicester on Tuesday night and Pellegrini revealed he will be out for at least another three to four weeks.
"Vincent has an injury, a second degree tear of the calf," said Pellegrini following the stalemate at the King Power Stadium.
"We will see how long he will be out, but I don't think it will be less than three to four weeks.
"I am not a doctor, but with a muscle injury, it will be very difficult for him to be back in less than four weeks. But without him, we must continue to defend as did tonight."
Kompany has started just eight Premier League games all season for City and the stalemate at the King Power Stadium was the first time Pellegrini's men have kept a clean sheet in his absence.
