The club can confirm that an agreement has been reached with FC Girondins de Bordeaux for the transfer of Malcom, subject to the player completing a medical and agreeing personal terms.
The Brazilian will arrive in Rome shortly in order to complete the final aspects of the transfer.
If all progresses well, Malcom will become the ninth outfield player signed by the club this summer - following the likes of Javier Pastore, Justin Kluivert and Bryan Cristante.
The 21-year-old has spent the last three seasons in Ligue 1. Last season he scored 12 goals in 35 league games for the side.
