Sir Alex Ferguson has confirmed that Manchester United are in talks to sign Brazil international Lucas Moura from Sao Paulo.
The likes of Real Madrid and Inter Milan have been linked with the 19-year-old midfielder, but United have moved into pole position in recent weeks.
Reports have claimed a deal worth around £26million had been agreed, but Ferguson insists this is not the case.
But for the first time he has confirmed he wants to sign the youngster, who has 11 caps for Brazil to his name.
"We haven't reached an agreement," said Ferguson from China, where United are on the latest leg of their pre-season tour.
"We've shown interest. Until such time we reach an agreement we can't say he's ours."
Ferguson, who is also bidding for Arsenal captain Robin van Persie and admitted to wanting another left-back earlier this month, says they are working hard behind the scenes.
"At this moment we're looking at other options in terms of bringing other players in," he said.
"We're not lying on our backsides doing nothing. We're trying hard to bring other players to the club."
Ferguson was asked about whether he ever made a move for former Chelsea Didier Drogba before his switch to China.
"He said he was going to leave Chelsea and not play again in England. So that eliminated everyone," he added.
