Manchester United are closing in on Sao Paulo star Lucas Moura.

R7 says negotiations over a deal to sign Lucas are at a delicate stage.

It is reported that agent Wagner Ribeiro is trying to aid a move but Sao Paulo president Juvenal Juvencio is holding out for the biggest possible fee and that could scupper any plans to bring the Brazilian to Old Trafford.

"It is a risk not selling Lucas but we are going to take it," said Juvencio.
