Daniele De Rossi has reportedly asked for a €6.5m a year salary in order to extend his contract at Roma.
The Italian international midfielder is only tied to the Giallorossi until June 2012, which means he could potentially leave on a Bosman free transfer next summer.
Roma are keen to keep the player given his Roman status, his ability and his transfer value, but they'd have to dig deep into their pockets to accommodate his requests.
De Rossi currently earns around €4.5m a campaign at the Stadio Olimpico. His alleged new wage demands would see him become the biggest earner in Giallorosso above even Francesco Totti.
Roma are hoping to construct a deal with a proportion of his salary fixed, but with various bonus clauses that could see his income rise.
Talks between the two parties are set to continue in an effort to reach a compromise.
Now 28, the midfielder has spent his entire career at the club after graduating through their youth academy.
Should De Rossi become available for transfer, he's likely to be wanted by almost all of Europe's top clubs.
Manchester City were linked with his signature during the summer, while Real Madrid have been paired with him on a regular basis over the years.
Roma start their Serie A campaign against Cagliari on Sunday.
