Johnson was Tottenham’s top Premier League scorer last season with 11, and etched his name into Spurs folklore by scoring the winning goal in the Europa League final over Manchester United in Bilbao, ending the club’s 17-year wait for a trophy.
But the departure of Ange Postecoglou and the arrival of Thomas Frank as the new head coach has meant Johnson has played a more peripheral role this season.
Johnson, 24, has only made six top-flight starts under Frank this season.
As a result, several clubs have been alerted to his possible availability ahead of the January transfer window.
Given his lack of action and the prospect of a World Cup on the horizon with Wales, a move away from Tottenham could suit Johnson next month.
Johnson joined Tottenham from Nottingham Forest in a deal worth £47.5m in the summer of 2023 and has scored 27 goals for the club.
