Chelsea rounded off their pre-season tour of Asia in style as they beat BNI Indonesia All Stars 8-1 in Jakarta on Thursday.
Jose Mourinho's side were 4-0 up at half-time thanks to goals from Eden Hazard, Ramires, Demba Ba and John Terry.
And they were equally clinical after the interval, with trialist Bertrand Traore getting on the score sheet, Ramires doubling his tally, and Lukaku grabbing the other two.
Tomas Kalas' own goal marked the only downside to the game for the Premier League side.
It took 21 minutes for Chelsea to get off the mark, Hazard tucking away a penalty after Terry was fouled in the box.
Ramires made it two eight minutes later with a powerful drive before Ba pounced following a strike from the Portuguese to put Mourinho's men 3-0 up.
There was just enough time before the break for Terry to head home the fourth.
The visitors came out for the second half with all guns blazing and added three more goals in a six-minute spell.
Traore curled home a beautiful effort with 50 minutes on the clock, Lukaku's header followed just two minutes later and Ramires' long-range strike made it 7-0.
The first of Lukaku's double came two minutes later, before Ramires completed his brace just short of the hour mark.
Lukaku got his second after 66 minutes before a Greg Nwokolo cutback went in off Kalas for the last of the goals.
