Bayern fearful of losing pair
Bayern Munich are concerned that they could lose star players Joshua Kimmich and Thomas Muller to Manchester City and Manchester United.
Both Manchester clubs are expected to splash the cash this summer in order to mount a title challenge next season.
Guardiola is keen to add to his defence when the window re-opens, and United are in the hunt for a world-class striker, with Zlatan Ibrahimovic potentially leaving Old Trafford after just one season.
Guardiola gave Kimmich his debut during his time in charge of the Bundesliga giants and could cough up £21million to land his man.
Muller, meanwhile, has reportedly indicated to Bayern chiefs he could leave for Manchester United. He has struggled for form this season, scoring just one league goal. He could join United should his struggles in the Bundesliga continue.
