Manchester United have already bid for the teenager this summer, whilst Inter Milan have also spoken to the 19-year-old.
However, neither United nor Inter have been able to meet Sao Paulo’s demands – which are reportedly around £45million (£35.7million).
Inter chief Massimo Moratti said on Tuesday that PSG had indeed made a bid which matched Sao Paulo’s valuation.
Now speaking to France-based newspaper Le 10 Sport, Sao Paulo vice-president Joao Paulo de Jesus Lopes has confirmed PSG have made contact.
“We have been probed by PSG about Lucas,” he admitted.
The Brazilian club’s official also confirmed that former Sao Paulo star and current PSG sporting director Leonardo was in regular contact.
“Leonardo has a very good relationship with Sao Paulo. But for now nothing is definite,” he added.
It is believed that PSG’s offer would see Moura remain in Brazil until January, but Lopes says the player will make the final decision on his future.
“The possibility exists but it is down to the player’s interests. The policy of Sao Paulo is to follow the desires of the player. If the player wishes to leave, Sao Paulo will not create any obstacle. But we must receive a proposal that is appropriate,” he said.
“It’s a financial issue. Paris Saint-Germain is a big club in European football and if the player’s interests and also the club’s are met, I do not see why it would not happen.”
