De Jong, who spent the second half of last season on loan at Newcastle United, has had the prospect of a long-term move talked up by his agent.
His brother, Siem de Jong, recently completed a £6 million move to St James' Park and that has seemingly sparked a new bout of interest from Alan Pardew's side, with De Jong's agent claiming that the two could be the "perfect match" playing alongside one another.
But why should the club sign a striker who scored no goals at all last season?
De Jong endured a tough spell after moving to Borussia Monchengladbach, struggling for both games and goals. Since his move to Newcastle, however, the 23-year-old failed to score once in 12 matches, only really impressing with his hold-up play.
A much more promising target is a man the Magpies had briefly been linked to in the past, although no concrete interest has been reported recently - Enner Valencia.
“I really like Italian football but if this jump to Europe happens, I will welcome it and try to do my best wherever I go.”

As Opta stats show, Valencia was the star of Ecuador's World Cup, scoring three times from just eight shots and winning seven dribbles.
The 25-year-old also scored 18 times for Pachuca last season, meaning he has the main ingredient that makes a clinical striker: goalscoring ability.
De Jong, however, is yet to prove that he can cut it at the top level. The fact that the Magpies have not yet registered concrete interest in Valencia, then, is one that must change.
