Roma's outstanding defender Mehdi Benatia continues to draw interest from Bayern Munich and Manchester United.
The saga over the Moroccan's future has continued all summer, with Chelsea and Manchester City also linked with his signature.
Roma have publicly insisted they want to keep him, but the 27-year-old is said to be keeping his options open.
So too privately be Roma, with a report surfacing in Italy that the Serie A side are covering their bases by drawing up a shortlist of potential replacements.
Il Messeggaro report the five players on their radar are Matija Nastastic (Manchester City), Rolando (Porto), Marko Basa (Lille), Kostas Manolas (Olympiakos) and Vlad Chiriches (Tottenham).
The most difficult player of the five to acquire may be Manolas, said to be in advanced talks with Arsenal, but given he would be backing up Per Mertesacker and Laurent Koscielny, they could tempt him with the promise of regular football.
Of the Premier League players listed, Matija Nastastic is thought to be available after the arrival of Eliaquim Mangala at Manchester City.
With Spurs interested themselves in Mateo Musacchio of Villareal, such an addition would see Vlad Chiriches take a step closer to the exit. Reports over the past few hours have suggested Roma have had an offer accepted for the Romanian. Neither Nastasic nor Chiriches made the benches for their respective sides during the Premier League's opening weekend.
