The Chilean has been linked with a move to a bigger club and these claims appear to have been substantianted by his representative, who says three heavyweights are tracking him
The 23-year-old is expected to depart the Friuli outfit in the summer as part of the club's annual selling to balance the books and Leo Rodriguez, who represents the versatile performer's playing interests, has revealed three of Europe's biggest sides have expressed an interest in his client.
"I think he is being tracked by Liverpool and other Italian clubs like Juventus and Roma," Rodriguez told BK Sport.
"I'm not sure that these clubs have already initiated contacts with Udinese."
However, it is also understood that he will not come cheap, with the publication also claiming Liverpool already saw a bid of €15 million rejected by Udinese in January.
