Chelsea boss Mauricio Pochettino is priortising the sale of three senior players.
The Blues manager is having to send some older players to train with the U21s as he doesn't have room to include them in first team training.
As many as 19 players have left the club this summer, but there remains 32 at Cobham training daily.
The London Evening Standard says the next three to leave will be Romelu Lukaku, Callum Hudson-Odoi and Malang Sarr.
All three have had offers to depart, but terms are yet to be settled either with the player or Chelsea. However, Pochettino has made it clear to the trio they have no place in his squad.
