The striker only joined the Blues last summer but found it hard going in his first season in England, managing just six goals in 35 Premier League appearances.
Werner remained a regular under Thomas Tuchel - starting the Champions League final against Manchester City and playing an important part in Kai Havertz's winner - but the summer arrival of Romelu Lukaku has, inevitably, dislodged him from the starting 11.
According to Sport 1 (via the Express), Bayern have discussed the possibility of a move for the Germany international - who scored in each of his country's three games during the latest international break.
The 25-year-old would find a starting berth equally hard to come by with the Bundesliga champions - a certain Robert Lewandowski stands in his way - but a return to a familiar league might do him the world of good and he could rival Eric Maxim Choupo-Moting as the main centre-forward back-up.
Werner bagged 78 Bundesliga goals in four seasons with RB Leipzig - where he played under new Bayern boss Julian Nagelsmann - including 28 in 2019/20, prompting Chelsea to trigger his £45 million release clause.
The Blues aren't exactly going to recoup that fee, but they have recently been linked with Leroy Sane - which potentially raises the possibility of some kind of swap deal for the former Man City winger.
