The 22-year-old striker has hit form during his loan move to Cercle Brugge in Belgium, having hit seven goals in 12 appearances.
Cercle have an option to sign him for €5million, but the London-born centre-forward is determined to carve a niche for himself at Chelsea - just as Abraham and Mount did after loan spells away from the club.
He told Sport/Foot: “I'm a true Londoner and, in my eyes, Chelsea will always be the biggest club in the capital.
“It's up to me to prove that I'm ready for an eventual return."
