The 17-year-old has been linked with clubs around Europe, including Inter, Real Madrid and several English clubs.
Lukaku’s agent confirmed Arsenal’s interest in signing his client earlier this week.
Lukaku’s agent has now also confirmed that Juventus are keen on signing the Belgium international.
Interviewed on Calciomercato.it, Lukaku’s agent Christophe Henrotay said: “There still aren’t any traces of official offers. But the English interest is real and we have a good relationship with them, but there is still nothing concrete.”
He added, when asked about Juventus and Inter: “I can’t define it as speculation because there has been contact with these teams.
“The interest exists and we often hear from them for updates on the player. Certainly something could happen at the end of the season, or maybe even before.”
