Alberto Aquilani's permanent move to Juventus could be in doubt after the Italian club's general manager, Giuseppe Marotta, said they would not pay Liverpool's asking price of £16 million.
Italy international Aquilani joined Liverpool from Roma for £17 million in the summer of 2009 but failed to make an impact at Anfield and was shipped out to Juventus on loan.
The 26-year-old has been a success in Turin and both player and club are eager to convert the season-long loan into a permanent deal.
However, Marotta said the club would not be prepared to pay the £16 million fee agreed with Liverpool when the loan move was put in place.
"There is a buy-out clause that has to be activated by May 15," Marotta told Sky Sport Italia. "We'll try to reach an agreement before the deadline. I can certainly say we will not sign Aquilani for the sum set by Liverpool."
Last month, Aquilani told Gazzetta dello Sport. "I would like to stay in Turin for a long time and win a lot."
