Ex-Bayern president has fuelled rumours linking Sane with a move away from Man City.
Bayern's move for the Germany international was hindered by a long-term injury.
The Bundesliga leaders are expected to sign Man City wideman Sane in the next transfer window.
Former Bayern Munich president Uli Hoeness believes Manchester City winger Leroy Sane will be a good addition to Hans-Dieter Flick‘s side.
Sane, 24, has been constantly linked with a move away from the Etihad, with the Bundesliga giants keen on securing his services as they look to build "a new era" at the Allianz Arena.
German winger Sane was a key player for Guardiola's side last season, making late runs in behind the opposition right-back from the edge of the penalty area that led to vital goals for the Citizens.
The former Schalke player looked set for a move to Bayern last summer before suffering a knee ligament injury in the Community Shield against Liverpool in August.
"I believe that we are on the threshold of a relatively great generation," he told BR.
"When I think that we managed to extend with Manuel Neuer, and we have Joshua Kimmich, Niklas Sule, Robert Lewandowski and hopefully David Alaba and Thiago Alcantara [also agreeing contracts], and I also hope with Leroy Sane, with [Kingsley] Coman, [Serge] Gnabry, a young, developable team.
"I can imagine, if everything goes well, that a new era is just beginning at Bayern Munich."
Bayern want to pay around £52m to £60m (€60m-€70m), according to Sky Sports, with Sane's contract set to expire next June.
