The forward is finally ready to leave the club that he has been at since he was 10 years old.
Anderlecht are considering Chelsea's Ike Ugbo as a replacement for Albert Lokonga who joined Arsenal for £18 million ($25m).
Fellow Belgian giants Genk are also said to be the other frontrunners for Chelsea's 22-year-old academy produced striker.
Chelsea are now considering raising the price tag beyond the initial £5 million ($6.8m) they previously set due to additional interest being received from clubs like Watford, Fulham, Bologna and Monaco.
