Sao Paulo vice-president Joao Paulo de Jesus Lopes has confirmed that Paris Saint-Germain are interested in signing Lucas Moura.The 19-year-old was previously linked with clubs such as Inter and Manchester United, but the Serie A side recently pulled out of the race to sign the winger, while no bid has yet been tabled by the Reds.Consequently, PSG now seem to be sitting in pole position to sign Lucas, with the Tricolor supremo now admitting that a transfer could be on the cards if the Brazilian is open to a move to the Ligue 1 giants."PSG have made an enquiry about Lucas. [PSG sporting director] Leonardo has a very good relationship with Sao Paulo, but no definite decision has been made yet," Paulo de Jesus Lopes told Le 10 Sport."It's a financial issue. Paris Saint-Germain are 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 could not happen."A transfer is an option, but it is up to the player to decide. Sao Paulo's policy is to listen to the player's desire. If Lucas wants to leave the club, Sao Paulo will not hamper a move. However, he will only leave for the right price."Lucas is currently representing the Seleccao at the Olympic Games in London and is expected to make a decision about his future once the tournament reaches its climax.
