Philippe Mexes has continued to stall on signing a new contract with Roma amid interest from Europe's biggest clubs.
The France international's current deal is due to expire at the end of the season and Roma have already expressed their willingness to push ahead with a renewal.
Mexes' stock has risen again this year and he has attracted admiring glances from Milan and Juventus who are aware of his situation.
The 28-year-old is unsettled at Roma, not least because of the ongoing ownership issues at the club.
La Gazzetta dello Sport understands that he would like to wait and see what the American consortium promise if and when their offer to buy Roma is successful.
Mexes' agent has already hinted that if his client does sign a new deal it will include a minimum fee release clause.
"For me there are more important things," Mexes said. "Now I am thinking about Roma. If I hurt myself, for example, everything changes.
"I have to think about many things. I am happy in Rome. I have a calm conscience."
Roma also have to resolve the future of another talismanic player in Simone Perrotta, as his contract is also due to run out.
