Arsenal is thought to have started informal conversations with Diego Costa about returning to the Premier League.
The 33-year-old is holding talks about his release from Atletico Mineiro and is likely to be available in January.
The Gunners are eager to add to their offensive options following the rumours around Pierre-Emerick Aubameyang's future, as well as the fact that Eddie Nketiah and Alexandre Lacazette's contracts expire this summer.
Mikel Arteta's side is one of several clubs in informal talks with the Spain international about a return to the Premier League, according to Goal.
Costa played at Chelsea for four years, collecting 59 goals in 120 games before returning to Atletico Madrid. The seasoned striker won two Premier League titles and one League Cup during his stint at Stamford Bridge.
Costa has five goals and one assist in 19 appearances for Atletico Mineiro, and is rumored to have a bid from Cadiz on the table.
