Manchester City has increased its options and experience at center back by signing Argentina defender Martin Demichelis on a two-year deal from Atletico Madrid.

City manager Manuel Pellegrini made his move for the pony-tailed Demichelis after seeing captain Vincent Kompany ruled out with a groin injury and Joleon Lescott, Javi Garcia and Matija Nastacic looking shaky in central defense in City's last two games.

The 32-year old Demichelis will be playing under Pellegrini for the third time in his career, having been together at River Plate and then in a loan spell at Malaga last season.

Demichelis, who has made 37 appearances for Argentina, says ''I am delighted to have joined City because I am still hungry for success and want to improve.''

Financial details about the deal weren't disclosed.
