Udinese want Juventus players in exchange for midfielder Gaetano D'Agostino.
The two clubs are locked in negotiations over the sale of Italy international D'Agostino to Juve.
Udinese want Sebastian Giovinco and Claudio Marchisio, but Juve coach Ciro Ferrara is reluctant to part with either player.
For their part, Juve have offered Paolo De Ceglie, Michele Paolucci and possibly Domenico Criscito in exchange for D'Agostino.
