The Dutch striker is looking to make his mark this season after a miserable first campaign.
The Dutchman joined the Magpies from PSV last summer in a deal which runs until 2020, but he endured a torrid first campaign after being struck down by injury.
The 28-year old managed just five appearances last season, and he will hope to have put his injury worries behind him after featuring in three of Newcastle’s first five games so far this term.
“I can certainly stay here for five years. Tim Krul has been here for 10 years… but it does depend on many factors ,” De Jong is quoted as saying by the Daily Star.
The forward also suggested a stint in America is on the cards when he enters the twilight of his career, adding: "I am adventurous, even though I played with Ajax for seven years.
"I would certainly look at the end of my career towards Los Angeles or New York. I've been a few times to the US. I travel a lot anyway."
Claims of his willingness to stay for another five years are unlikely to be met with jubilation among the Toon Army, and De Jong now has to prove that he can produce consistently and keep out of the medical room for a sustained period of time if he is to win over their support.
The target-man boasted an impressive strike rate during his seven years at hometown club Ajax - averaging more than a goal every three games – and it’s this type of form that needs to be replicated in the Premier League.
