Over the course of the season, the 25-year-old has reinvented himself at St. James' Park, particularly since Eddie Howe's appointment as boss in November, and has played a starring role in the Magpies' climb away from relegation danger.
Now deployed in the middle of the park, Joelinton is one of the first names on Howe's teamsheet, excelling from box to box and gaining more and more admirers - both on and away from Tyneside - with each passing week.
The former Hoffenheim man's struggles as a number nine, which saw him net just six times in 69 Premier League appearances during his first two seasons at the club, already feel like a distant memory.
After being presented with the award, the Brazilian beamed: "I'm delighted and very happy to win this award. Thank you to the fans, the players and the staff for helping me, and all my family and friends. Thank you.
"It has been a great season for me. Many things have happened, but I'm very happy to help the team and help the team stay in the Premier League. Hopefully next season will be even better."
