Atletico Madrid are reportedly interested in signing Arsenal attacker Santi Cazorla in the January transfer window.
The 29-year-old is believed to be unsettled in London and has been strongly linked with a return to Spain in recent weeks.
The Spaniard, who only has 18 months remaining on his current deal, moved to the Gunners from Malaga in 2012.
According to the Daily Star, Atletico will launch a bid in January, but could face competition from a number of European clubs.
Cazorla has scored just twice for Arsenal this season.
