Lukaku has offered a direct apology to Chelsea supporters in a bid to build bridges after his controversial interview revealing unhappiness at Stamford Bridge.
The club-record signing has already apologised internally at Chelsea and returned to training, but has now moved to address Blues fans personally.
'To the fans I'm sorry for the upset that I've caused,' Lukaku told Chelsea's official club website. 'You guys know the connection I have with this club since my teenage years, so I totally understand you guys being upset.
'Obviously it's up to me now to restore your trust, and I'll do my best every day to show commitment on the training ground and in games to make sure we win games.
