Manchester City defender Aleksandar Kolarov sidelined for at least a month

Manchester City defender Aleksandar Kolarov has been ruled out for at least a month with a calf injury.

The full-back suffered the problem on Sunday during the warm-up before his side's 1-0 win over Manchester United in the Premier League.

City manager Manuel Pellegrini told reporters on Tuesday: "Kolarov has a muscle injury in his calf – he will be out for at least one month."

The Blues are back in action on Wednesday when they host CSKA Moscow in the Champions League.
