'Tuttosport' ran the headline "Juventus, there's De Ligt!'" on Tuesday, claiming that the Turin-based club are set to hijack a possible Barcelona deal.
Ajax have gone on record to state De Ligt's unavailability, however they may be tempted with a lucrative offer from Juve in January.
Marc Overmars told 'LaRoma24' that, "The probability of De Ligt leaving Ajax in January in zero", however 'Tuttosport' think differently.
Ajax are holding out for £44m, however it is understood that they will allow the 19-year-old to discuss personal terms with 'The Old Lady' if they meet this fee.
De Ligt, who made his debut for Ajax just two years ago, is now the club captain and produced a polished performance at Bayern Munich in the Champions League last month.
Barcelona scouts were present to watch the Dutchman during Holland's win against Germany on Saturday night and saw him impress alongside Virgil van Dijk.
De Ligt has made seven Eredivisie appearances for Ajax this season, scoring the one goal.
