Roma winger Daniele Verde has reportedly emerged as a potential transfer target for Porto.
The two clubs have already conducted business since the end of the last campaign, with Ivan Marcano leaving the Portuguese giants to move to the Stadio Olimpico.
Roma have remained proactive during the early stages of the summer window and according to Gianluca Di Marzio, it has resulted in Porto taking an interest in one of the fringe players at the Italian club.
Verde came through the youth setup at Roma but the 21-year-old has only made 10 appearances in the first team and spent last season on loan at Verona.
The attacker has two years remaining on his contract with Roma, but the Serie A outfit could potentially be open to a deal with three additions having already been made and the acquisition of Justin Kluivert from Ajax close to completion.
