Roberto has endured a difficult season at Barcelona having been ousted at right-back by summer signing Nelson Semedo.

The player's contract at the Nou Camp expires in 2019 and, until that runs up, clubs can sign him by activating his £35million release clause.

Roberto is a close confidant of Messi, with the two having known each other dating back to the former's time in the Barcelona academy.

And Spanish website Don Balon claims Messi has learned Juventus are prepared to activate Roberto's release clause and bring him to Turin when the transfer window opens in January.
