Sao Paulo vice-president Joao Paulo de Jesus Lopes has revealed that Manchester United and Real Madrid have both made offers for Lucas.
Speculation over the 19-year-old's future has intensified in recent days after the player admitted that he may leave Brazil before 2014, unlike Selecao team-mate Neymar.
Inter have long been linked with Lucas, and the gifted attacker has publicly declared that he would jump at the chance to join the Italian giants.
However, Jesus Lopes claims that he has not yet heard from the Nerazzurri, but indicated that the Red Devils and the Spanish champions have already launched offers for the player.
"I can say that we have not yet received an official offer from Inter for Lucas, nor have we received any information about any proposal from them," he told FCInternews.it.
"With regards to the offers from Manchester United and Real Madrid, we are studying them internally. We cannot say anything else for obvious reasons.
"Everyone knows that there is a release clause of €80 million for all those who want to sign Lucas."
