It’s not just Italian papers. Tier 1 sources for Napoli have reported and even Paris United is carrying the story. The guy that runs CulturePSG participates on its forum and has decent sources. He’s confirmed as well.
Henrique fucked up the De Jong transfer, yes, but I don’t think he’s valued by Tuchel the same way Allan is.
Edit: There’s a lot of rumors about the deal being financed through a Qatari Airways shirt sponsorship.
They talked about the fact we are interested in him, which is normal Allan being a good player. They, however, are very doubtful about the price and the likelihood of the deal. No reputable sources bar the italian ones are reporting that sponsorship nonsense.
It is the same kind of rumors with Neymar being paid as a WC 2022 ambassador and being then free for PSG. It never happened.
For Qatar Airways, it would be a bad deal to sponsor two teams from the same league (they already sponsor Roma).
PSG not willing to pay 90 M for Ajax but so swift to pay 100 M for Allan ? Nah, don't believe it one bit.
PSG spends that much only on stars or hype up youngsters like Mbappé, de Jong (and even for him they didn't).
