Sao Paulo vice-president Joao Paulo de Jesus Lopes still believes an agreement can be reached with Manchester United for Lucas Moura.
Moura's agent Wagner Ribeiro yesterday suggested there was little chance of the 19-year-old joining United this summer as the Red Devils had fallen short in their bid for the Brazilian youngster.
However, Lopes insists the door is not closed to Barclays Premier League outfit, telling Radio Estadao ESPN: "I don't rule out the possibility that in the future there are some sort of negotiations, because we received Manchester [United] with great courtesy and left open the possibility of more talks.
"Manchester [United] came to us and their approach was serious. Other teams expressed an interest for Lucas, but only through the media in their countries."
Lopes did warn, though, that Lucas, who is currently in England with the Brazil Olympic squad, is happy to remain at home-town club Sao Paulo.
"The player has expressed his intention to remain at Sao Paulo, and is a very important player in our squad. He wants to stay because he is very young," he added.
