Chelsea are seeking offers for a raft of manager Frank Lampard's squad.
The Daily Mail says Chelsea are upgrading their squad with talks ongoing with Bayer Leverkusen over a fee for Kai Havertz.
Lampard also wants another goalkeeper and a centre back.
They have lost Willian and Pedro while they will consider offers for Marcos Alonso, Ross Barkley, Michy Batshuayi, Danny Drinkwater, Emerson Palmieri, Davide Zappacosta and Tiemoue Bakayoko.
Bakayoko currently has an offer from AC Milan.
