Released Atletico Mineiro striker Diego Costa has attracted an approach from Arsenal.
Goal says the Gunners are one of several clubs to have held informal talks with the 33-year-old.
While the report noted Arsenal have not submitted an official enquiry for the former Chelsea striker, Mikel Arteta remains eager to bolster his attacking options during the January transfer window.
With the out-of-favour Pierre-Emerick Aubameyang on international duty at the Africa Cup of Nations and Folaring Balogun loaned to Middlesbrough this week, Arsenal's choices up-front are limited.
Costa is ready to return to Europe and has also fielded interest from Spain, where Elche and Cadiz are in contact.
