Manchester United and Chelsea are watching squad developments at Bayern Munich.
Kicker says Bayern will sell either Thiago Alcantara or Arturo Vidal in the summer.
Vidal and Thiago's future in Bavaria is under threat following the capture of Leon Goretzka from Schalke.
Allianz Arena chiefs could now cash in as they look to reshape the squad with younger faces.
It's believed United boss Jose Mourinho is keen on swooping for Vidal, who was strongly linked with an Old Trafford switch during the Louis van Gaal era.
Chelsea are also said to be interested, despite question marks hanging over Antonio Conte's future.
