Atalanta have reportedly opened talks with Gremio over a possible deal for striker Luan.
According to Globo Esporte, Atalanta are ready to add Luan to their attacking arsenal and the situation could develop quickly.
The 26-year-old has scored 72 goals in 274 appearances for Gremio in all competitions and has two caps for Brazil, while winning Olympic gold with his country in 2016.
He is known for his versatility, which also lets him play on either wing or as a second striker, and is a prolific source of assists, having set up 12 goals in the League and Copa Libertadores since last year.
Luan was previously linked with Barcelona, who eyed him up as a backup to their front three of Lionel Messi, Luis Suarez and Neymar in 2016.
