The Serie A champions have already seen Carlos Tevez, Andrea Pirlo and Angelo Ogbonna leave this summer.
And it seems as though Vidal, who had also been linked with Arsenal, will follow the trio out of the exit door to join Pep Guardiola at Bayern Munich.
???We???ve always said we won???t sell players unless the players indicate that???s what they want,??? Marotta told a press conference.
???That???s how it was. Tevez asked to return home to Argentina. Pirlo made some assessments, and decided he wanted a new experience.
???Ogbonna asked for opportunity and consistency in playing time, and as for Vidal, I asked him before I went to meet the Bayern Munich leadership.
???He confirmed he wanted a different experience. I???d also emphasise that the player had a contract ending in 2017, while they???re offering him a five-year contract, and that???s very important for his future.
???We???re not a selling club, we???re attentive to those who can increase our quality level.???
The move is yet to be finalised but Vidal looks poised to leave Juve after four years and four Serie A titles.
He joined the Italian side in 2011 from Bayer Leverkusen, where he made more than 100 appearances over four seasons.
