Lukaku, 28, is on the verge of sealing a dramatic return to the Blues, seven years after being allowed to leave Stamford Bridge.
The Belgian striker completed the first part of his medical in Italy on Monday as his £97.5m transfer from Inter Milan edges ever closer.
He is now expected in London to sign a five-year contract worth a colossal £200,000-a-week and complete remaining checks.
Italian journalist Egle Patane captured the moment Lukaku arrived at a Milan airport to board a flight to the English capital - but the forward wasn't in the mood to give too much away.
