Lukaku is due to re-sign on-loan for Inter from Chelsea.
Immobile said, “I don't think about records. I will certainly realise the extent of what I have done in the world of football once I stop playing. It's clear that we mustn't rest or give up.
“With Lukaku back in Italy, the level of our league is raised, I will have to continually do my best.
"Now I only have the next objectives in my head."
