Frank Lampard is in temporary charge.
Chelsea have met face-to-face with Julian Nagelsmann as they continue their search for a new manager.
Co-sporting directors Laurence Stewart and Paul Winstanley flew to Germany last week to hold talks with the recently sacked Bayern Munich boss.
Luis Enrique and Mauricio Pochettino are also among the rumoured candidates.
Frank Lampard's in charge until the end of the season, after Graham Potter was dismissed.
