Juventus are reportedly not prepared to sell Matthijs de Ligt during this summer's transfer window.
The Italian champions won the race for the Netherlands international ahead of the 2019-20 campaign, allegedly beating the likes of Manchester United to the centre-back's signature.
De Ligt has found it difficult to show his best form since arriving in Turin, though, and there have been suggestions that he could leave the Old Lady this summer.
United are reportedly interested in signing the 20-year-old as part of a swap deal involving Paul Pogba, but according to Tuttosport, Juve will refuse to sell the Dutchman this summer.
De Ligt's agent Mino Raiola has also allegedly invited Real Madrid to make an offer for his client, who has made 27 appearances for Maurizio Sarri's side during the current season.
The centre-back helped Ajax win a league and cup double last term, in addition to playing a key role in the Dutch side's run to the semi-finals of the Champions League.
