Gordon, who made his Premier League debut for Everton in January 2020, becomes Eddie Howe’s first signing of this January transfer window as the third-placed Magpies bolster their attacking options for the second half of the season.
The young forward was heavily linked with a move to Stamford Bridge in the summer while Thomas Tuchel was still manager in order to add options to his frontline but, a move ultimately fell through with the Blues unprepared to meet Everton’s asking price.
He becomes the latest in the Toffee’s squad to leave after such a disappointing season, following the dismissal of manager Frank Lampard.
