Liverpool will have to pay €40m to sign a star on their shortlist. They haven't struck a deal like this for 20 years.
Liverpool have been heavily linked with a move for Allan in recent days. Reports, almost entirely out of Brazil, suggest they lead the race for Palmeiras's latest gem.
'The Football' is one such local report. They claim Liverpool are the preferred buyer for the 21-year-old, despite interest from elsewhere.
The suggestion is that Palmeiras would like to open a dialogue with Liverpool. That potentially leads to more deals down the line - or at least, another elite club willing to buy players off of them, driving up the price of anyone they try to sell.
That's something they've already done with Real Madrid (Endrick) and Chelsea (Estevao) in recent years. Now the Reds could join that list.
But it's a difficult deal. In fact, Liverpool haven't struck a deal like this for many years.
Liverpool go again with Allan
IG in Brazil reports that there's certainly no deal with Liverpool just yet. They also make it clear that Allan won't come particularly cheap.
The 'The Football' report claims a price of around €35m would be necessary but Allan is almost certainly going for more than that. As IG point out, Palmeiras rejected a €35m offer from Napoli in January that would have reached €40m with bonuses.
It feels safe to say that Liverpool would need to pay at least €40m essentially guaranteed if they're to get this one done.
And while reports are positive in that regard, this would be a bit of history for the Reds. They haven't signed a wonderkid from Brazil - someone playing at the top level and with genuine hype around them - since Lucas Levia in 2007.
Lucas was voted the best player in Brazil the previous season, following in the footsteps of Kaka, Alex, Robinho and Carlos Tevez the four years before him. Allan doesn't have quite that pedigree but he's undoubtedly an elite prospect.
And one who might just end Liverpool's near-20-year wait for another Brazilian wonderkid.
