Lucas Moura's agent says he has been instructed by the midfielder to "keep negotiating" with Manchester United , but the Brazil international would also be happy to stay at Sao Paulo.
United manager Sir Alex Ferguson confirmed on Monday that talks have been held regarding a deal for the 19-year-old.
Sao Paulo claim to have rejected a £25.6million offer from United and are holding out for £30m, with Moura's representative Wagner Ribeiro subsequently stating the Premier League club will not increase their bid.
Ribeiro also confirmed that he had no plans to hold talks with the Red Devils during a trip to England to watch Moura play for Brazil at the Olympics.
However, Ribeiro is keeping the door open regarding a move to Old Trafford after saying Moura is happy for talks with United to continue.
Ribeiro, though, also admitted that the highly-rated midfielder has no problem remaining with Sao Paulo, if the Brazilian club's demands are not met.
"The player is my boss, I always talk to him," Ribeiro told Radio Globo.
"He determines what I do, my objectives. If he says that he doesn't want to leave Sao Paulo, I won't even listen to the offer.
"He told me to keep negotiating when I talked about Manchester United's interest.
"It's a great offer. If it was an irrecusable one, he would leave, but he is happy at Sao Paulo too. If he stays there, life goes on."
