Martin Demichelis has signed for Malaga to the end of this season.
The former Manchester City defender is returning to La Rosaleda for a second spell, having played for the Andalusian club between 2011 and 2013 after joining from Bayern Munich.
The 36-year-old was available as a free agent after leaving Espanyol earlier this month.
A Malaga statement read: "Centre-back Martin Demichelis will play in Malaga for the rest of the 2016/17 season.
"The Argentinian, who has a wealth of experience among the elite of European football, will be having his second stint with the club, where he has played more than 100 games in LaLiga, Copa del Rey and Champions League."
