Romelu Lukaku has promised to return to Anderlecht at some point in the future, while describing former Belgium assistant Thierry Henry as his "mentor".
Lukaku rose through the youth ranks at Lotto Park before graduating to the senior squad in 2009, and went on to score 41 goals in 98 appearances for the club.
