The 21-year-old centre-back came through the academy ranks of Juventus and last season went out on loan to Empoli.
De Winter made 14 league appearances for Empoli in the last campaign before missing part of the season due to an injury.
His performances have caught the eye of Everton boss Sean Dyche, who is interested in bringing the Belgian to Goodison Park.
Now, according to Italian daily Gazzetta dello Sport (via Tutto Mercato), Everton are not the only suitors for De Winter on the market, as unnamed Championship clubs are showing interest in him.
De Winter is highly rated at Juventus and the Serie A outfit are not keen on parting with him.
It is said that Everton have already made an enquiry regarding the availability of the centre-back but have yet to submit any offer for him.
Now it remains to be seen whether any of De Winter’s Championship admirers will make a move to secure the defender’s signature this summer.
