A deal to take the Italy international back to Serie A could be held up over a wage issue as talks regarding a move continue, with the midfielder keen on Anfield exit
Despite impressing for Liverpool in pre-season, the player's representative confirmed talks over a move back to Serie A for his client have been taking place.
Aquilani, 27, is seen by Fiorentina as an alternative to Riccardo Montolivo, who has been tipped to leave the club this summer, possibly for AC Milan.
Zavaglia has now said there is an agreement between the two sides for the transfer, but it seems the player's wage demands are holding up the move.
"The accord between Alberto and Fiorentina has not been reached yet," the agent told La Gazzetta dello Sport.
"If we speak about an agreement, then one has only been reached between the two teams.
"However, with us, Fiorentina have still not made a decision."
It seems the negotiations between all parties are set to continue until an agreement is found.
When contacted about the deal, Liverpool refused to provide a comment on the latest developments.
Aquilani has made no secret of his desire to return to Serie A and play regularly ahead of next year's Euro 2012.
The latest reports from Italy suggest the agreement between the clubs is over a loan with Fiorentina having the option to buy for around £9.7 million next year.
