Poland striker, Robert Lewandowski, has one year left on his Bayern Munich contract, placing Chelsea, Manchester City and other suitors on alert.
UK Sun, quoting unhappy new manager, Julian Nagelsmann, reports that Lewandowski's uncertainty has clubs 'putting out feelers' over a transfer.
Lewandowski joined Bayern from Dortmund in 2014 on a free transfer and his Allianz Arena contract runs until 2023.
Chelsea who are eyeing £150million-rated Borussia Dortmund ace Erling Haaland and Manchester City who have eyes on Tottenham star Harry Kane are thought to be interested in the 32-year-old.
Meanwhile, Lewandowski's contract situation has left Nagelsmann who replaced Hansi Flick unhappy.
The former RB Leipzig boss said: "I think it's normal for someone who scores so many goals that almost every club puts out a feeler.
"I think on one hand Robert knows what he has in Munich, what he has in this team.
"I've already spoken to him and texted him. I'm not very fond of the first official act with a player being to immediately discuss his contractual situation."
After seven trophy-laden seasons with Bayern, Lewandowski has gone to score an incredible 294 goals in just 329 appearances.
