Manchester United have suffered a setback in their chase to sign South American starlet Lucas Moura, after the Brazilian Football Confederation said that it would refuse to release the player for a medical should a request be made by the club.
The 19-year-old midfielder is expected to play for coach Mano Menezes' side in their Olympic semi-final against South Korea at Old Trafford tomorrow.
The confederation said that United had not made a request after a report that a £30million bid had been accepted by Sao Paulo.
"The board of the Brazilian football has not received a request from the English club and if we receive one, we will not allow the player to leave the camp to do it," read the statement.
Sir Alex Ferguson is eager to complete the capture of Lucas, who will be tasked with providing extra creativity and flair, to a Red Devils midfield that has already been strengthened with the summer signings of Japanese international Shinji Kagawa, and Crewe Alexandra's teenage sensation Nick Powell.
Inter Milan, Paris Saint-Germain and Real Madrid have all reportedly been interested in Lucas, but it appears United have prevailed, after the Premier League giants were given the green light to hold talks with the teenager after tracking him for most of the summer.
