The 22-year-old midfielder is widely regarded as one of the best talents in South America and is soon expected to move to Europe.
Several European clubs have been keeping tabs on the player, with Liverpool especially keen, having explored a move in the summer and now looking towards a January deal.
However, the Merseyside giants are prioritising defensive options, while Manchester United have only made an enquiry.
And Fulham have used the opportunity to move ahead of Liverpool in the chase for Andre’s signature.
Mackintosh was in Brazil last week to hold face-to-face talks with Fluminense and the player about a potential move in January.
A £30m move is being discussed and Andre is keen on a move to the Premier League in the winter window.
Marco Silva is a fan of the 24-year-old and wants to add him to his Fulham squad in January.
It was suggested just days ago that an unnamed Premier League side are preparing to bid for Andre and Fulham could be that club.
Missing out on Andre would be a big blow to Liverpool boss Jurgen Klopp, who is a big fan of the player.
