Bayern Munich officials fear competition from Manchester United for Fiorentina winger Federico Bernardeschi.
The Italy international could be on the move this summer after rejecting Fiorentina attempts to open new contract talks.
Chelsea and Juventus are keen, with the latter tablong €40 million for the midfielder. However, the Viola have no plans to sell to a Serie A rival.
BILD says Bayern are also chasing Bernardeschi, but have learned of rival interest from United.
Given Juve's proposal, Fiorentina patron Diego Della Valle believes they can generate €50 million from Bernardeschi's sale.
