None of the Potters' strikers have scored more than two league goals this season and Hughes is keen to strengthen in the New Year.
De Jong's future at Borussia-Park appears to be uncertain following a fall-out with manager Lucien Favre.
The 23-year-old has made 11 Bundesliga appearances this season, but all have been as a substitute.
According to The Mirror, De Jong is desperate to leave Monchengladbach in order to boost his chances of earning a place in Holland's World Cup squad.
The paper also claims that Stoke are keen to offer De Jong first-team football and that the Potters sent a scout to watch him appear for seven minutes during Saturday's 2-1 win over Schalke 04.
