Udinese admit Gaetano D'Agostino's move to Juventus could fall through.

"The negotiations for D'Agostino's switch to Juventus has entered an impasse that it is difficult to get out of," Udinese director general Sergio Gasparin told Radio Radio.

"When we pin-pointed the players we were interested in, Juve put up obstacles. Therefore it is an uphill struggle now to complete this sale.

"We did not want to release D'Agostino anyway, but unfortunately when a big club like Juventus makes an offer, it is our duty to approach it the right way."
