Reports in Brazil suggest that Manchester United have had a €38 million bid for Sao Paulo youngster Lucas Moura rejected.
Lucas, 19, is a major target for Manchester United this summer, who are believed to have officials in Brazil working on a deal and saw an earlier €32 million bid turned down.
The Brazil midfielder, who flew to London on Tuesday to take part in the Olympic Games, was thought to also be a target for Italian giants Inter Milan, but the Serie A side are reportedly unable to meet the player's asking price.
Sao Paulo president Juvenal Juvencio is reluctant to sell his starlet, believing Lucas to be an important player in a potential Copa Libertadores challenge.
Globo Esporte quote a source close to the club hierarchy as saying: "Football is about winning titles and there is nothing more important. He will be an important player in any titles this club may win."
Lucas, who is in the process of negotiating a new deal at the Brazilian side, is known to be interested in a move to Europe, with his current salary less than €100,000 a month.
Sao Paulo, though, are determined to hold onto their prized asset, as Juvenal Juvencio looks to build a side capable of success, despite United's reported offer meeting their initial asking price.
