Manchester City have confirmed that new signing Martin Demichelis will be out for approximately six weeks after picking up a knee injury in training.
The defender joined the club from Atletico Madrid towards the end of the transfer window on a two-year deal that sees him link up with Manuel Pellegrini who he worked with at Malaga last season.
However, 32-year-old is set for a spell on the sidelines after Manchester City confirmed he had undergone a scan which showed he had suffered knee ligament damage, although he will not need surgery on the problem.
Demichelis's injury leaves Pellegrini with selection problems in defence, as captain Vincent Kompany is currently side-lined with a groin injury while Micah Richards has a hamstring problem and Matija Nastasic is only just back in action after an ankle problem.
City's defensive woes have seen them forced to use Javi Martinez in defence this season alongside Joleon Lescott, during the club's shock 3-2 defeat at Cardiff.
