Inter Milan could reportedly agree to sell Lautaro Martinez to Barcelona this summer if the Spanish champions offer up three players in exchange for the Argentine.
Barca continue to be strongly linked with a move for Martinez, who has scored 16 times in 30 appearances for Antonio Conte's side during the 2019-20 campaign.
Inter are seemingly determined to keep hold of the South American, but according to Mundo Deportivo, the Italian giants would consider a sale if Barca agree to offer three players in exchange.
The report claims that Brazilian midfielder Arthur is wanted by the Milan giants, in addition to Carles Alena and Jean-Clair Todibo, who are currently on loan at Real Betis and Schalke 04 respectively.
Arthur has had his injury problems this season but has featured in each of Barca's last seven league matches.
Alena and Todibo are thought to be surplus to requirements, though, with both players allowed to leave Camp Nou in January in search of regular football.
