Lukaku had to field questions from the media on his family background, a deal he is eyeing with a car manufacturer and a “betrayal” at Manchester United that failed to materialise.
Lukaku was speaking before Manchester United take on Tottenham at Old Trafford in the Premier League on Sunday.
It has been reported that Manchester United want a deal in place by the end of the month.
“I think every footballer has a lot of time to let you know his people, his management,” Lukaku said.
“I don’t know which person you are talking about. He has to let me know if I can help him out. I will try to help him, but he is not my manager.”
Lukaku made light of the comments by the Intercontinental-listed company because he has an agreement with a German sportswear firm that will make him the second-highest paid athlete in the world.

“If you know exactly who you are talking about, then I will know and I can help you out. But if you think you are talking about a player, then you have to give me information if I can help you,” Lukaku added.
“I don’t have to know if you are talking about a manager or whether I am on the list of people at Man United – not because I’m not the top manager there.
“If you don’t know who I am, I will understand that I will be the highest paid athlete – but I can’t give you my employees.”
Lukaku has also posted an advert on his social media accounts for a commercial agency, and is alleged to be in discussions with a company for a reported seven-figure deal.
