Arsenal are watching Malaga goalkeeper Willy Caballero.
The Argentine, 30, has been a surprise revelation for Malaga this season, having only moved to the big spenders in January from little Elche.
Cadena Ser says his form has attracted the attention of Arsenal and AC Milan.
Gunners boss Arsene Wenger is in the market for a new keeper with Manuel Almunia likely to leave, having signed on-loan with West Ham United last week.
