Everton defender Nathan Patterson is set to be on the move.
The young Scot will be sent to the Championship on-loan for the new season.
Blues boss Frank Lampard is keen to sign a new right-back and wants Patterson to continue his development elsewhere.
Everton have already sent Jarrad Branthwaite on loan to PSV Eindhoven, with Joao Virginia joining SC Cambur.
Meanwhile, Jonjoe Kenny and Cenk Tosun have departed on free transfers.
