Lucas Moura's agent has claimed a proposed move to Manchester United will not go through unless Sir Alex Ferguson meets Sao Paulo's asking price.
The Scot confirmed his interest in the 19-year-old winger in Shanghai yesterday, but denied claims that the two clubs had reached agreement over a £26million transfer.
Now the player's agent, Wagner Ribeiro, has warned United they have little chance of prising the teenager away from South America unless they match Sao Paulo's valuation, which is significantly higher.
Ribeiro told http://www.uol.com.br: "They have reached their limit, they will not offer anything more. He will not leave. He is happy in Sao Paulo.
"This matter has to be terminated, there is no possibility of him leaving now.
"Manchester United made an offer which was refused, and will not do another because they came up to their limit."
Ferguson, who has already added midfielders Shinji Kagawa and Nick Powell to his squad this summer, admitted Lucas is among his remaining targets during the Red Devils' pre-season trip to China.
He told a press conference: "We have shown an interest, but until such time a we get a deal agreed, we can't say he's our player."
