Toni Rudiger is yet to sign a new deal with Chelsea.
With his contract set to expire in June, the Germany defender is delaying a new agreement with the Blues while weighing his alternatives.
Negotiations between the two sides, according to Italian transfer market specialist Fabrizio Romano, are still ongoing.
Rudiger has been requesting a re-signing fee of €10 million each year.
Bayern Munich and Paris Saint-Germain are keeping a careful eye on the situation, knowing that they may sign Rudiger to a pre-contract deal as early as January 1.
