The midfielder's current contract with Barcelona expires in the summer of 2026 - and it has been reported for some time the Catalans want to extend his contract.
However, De Jong is said to want to wait for an extension - and Barcelona plan to sell this summer if a new contract is not signed by then.
Sport says De Jong is now open to leaving Barcelona.
It didn't take long before interest in the midfielder began emerging and three major clubs have the Dutchman on their radar.
Paris Saint-Germain are also following the midfielder - but the most intense interest is said to be in the Premier League.
