However, although he is aware of the rumours, Vidal says he is concentrating solely on Bayern's treble charge this season.
"Yes, I've heard about it, but I'm fully focused on the season with Bayern and I'm only looking day-to-day," the Chilean said after Bayern's 5-3 friendly win over Sonnenhof Grossaspach on Tuesday, as quoted by Sport.
"We're a great team and we have big goals. We want to win every trophy. That's what my focus is."
Head coach Jupp Heynckes insisted earlier this month Vidal would not be sold during the transfer window.
The 30-year-old has made 14 Bundesliga appearances this season, scoring five goals.
Bayern resume their title defence against Bayer Leverkusen on Friday.
