At the age of 34, Dzeko is still going strong and last season delivered 19 goals and 14 assists.
The Bosnian has yet to give any indication that he wants to leave the capital club, where he is the captain.
Dzeko is a vital player for Roma and with their €591m takeover now complete, the club is under less pressure to sell players.
If Dzeko does tell Roma bosses that he wants to leave, they may then, and only then, consider a sale.
But Di Marzio reports that if Dzeko did join Juventus, Milik could be the man to replace him at Roma.
