The Magpies midfielder is out of contract at the end of the season but he is eager to get the required number of appearances to trigger a new deal.
The 31-year-old midfielder has been on the Magpies' books since the summer of 2016 when he joined from Hull City for a transfer fee reported by Chronicle Live to be worth £3.5 million.
Diame is currently the only senior Newcastle player whose contract expires at the end of the 2018/19 campaign (Transfermarkt) but, according to the Chronicle, a new deal will be triggered should he reach a certain amount of matches.
Newcastle manager Rafael Benitez has made extensive use of the Senegal international this season, with 17 Premier League appearances under the player's belt so far for a total of 91 in the black and white stripes.
When asked by the Chronicle about his future at St James' Park, Diame replied: "It's very nice for me at Newcastle and I am happy here. Everyone knows I am near the end of my contract. But I am really happy and I hope to stay more years here.
"The situation is weird because I have an option. Right now as we speak, I will be out of contract... I'm happy because I am playing and if I am playing and doing well, Newcastle will extend my contract."
During the 2017/18 campaign, Diame - who earns £45,000 per week, the joint second highest at the club, according to Spotrac - made 23 starts and eight substitute appearances in the Premier League for Newcastle, scoring two goals in the process, according to Whoscored.
