Manchester City boss Manuel Pellegrini in the dark on Sergio Aguero return

Manchester City boss Manuel Pellegrini insists Sergio Aguero’s injury is not serious but he is still unsure when his leading striker will return.

Aguero has missed two games since limping out of last month’s victory over Southampton with a heel injury and the Argentine star striker will again be absent as they host Borussia Monchengladbach in the Champions League tonight.

Both manager and player have played down the problem but the 27-year-old also seems unlikely to return before the Barclays Premier League visit of Swansea on Saturday.
