Everton and Newcastle have been placed on red alert regarding the future of Thomas Muller.
The veteran German is not happy at the lack of contract talks at Bayern Munich, and may be considering his future.
The 33-year-old, who has nine goals and 20 assists this term, is out of contract in 2023.
Bayern are in talks to extend first team stars Manuel Neuer and Robert Lewandowski.
Speaking to Bild, Muller said: "No one has ever approached me from the club.
"So you have to see what the future will bring."
