Manchester United are reportedly in official talks with Sao Paulo over a deal to sign winger Lucas Moura.
The 19-year-old has been named in Brazil's football squad for this summer's Olympic Games and United are said to be desperate to secure his signature prior to the tournament beginning on July 26.
According to The Mirror, the Old Trafford club have made an initial bid of more than £20m for the player and are likely to increase their offer later this week.
Inter Milan, Chelsea, Real Madrid, Manchester City and Liverpool have all been linked with moves for Lucas within the past three months.
