Europe's biggest clubs are on red alert as Bayern Munich prepare for an all-star clearout this summer.
The Daily Mail says Bayern are willing to listen to offers for Jerome Boateng, Thiago Alcantara, Juan Bernat and Arturo Vidal.
Boateng has been linked with Liverpool, while Vidal is interesting Napoli.
The German champions want to cut down the size of their squad for new coach Niko Kovac but want to resist offers for Robert Lewandowski.
Lewandowski has been repeatedly linked with a move away from Allianz Arena and is desperate to fulfill his desire to win the Champions League.
