According to ESPN Brasil, Tottenham have decided a loan is not an option and will only sanction Richarlison's departure for an outright fee of around €20 million, a steep reduction on the roughly €58 million they paid Everton for the forward four years ago.
The stance reflects how far the 29-year-old has fallen out of the club's plans: he was not even registered for this season's Premier League squad, ruling him out of involvement regardless of any change of heart from the coaching staff.
A return to his homeland appeared to be on the cards in the closing days of the summer window, with Vasco da Gama making contact over a potential deal, but the move ultimately collapsed before it could be completed.
Richarlison's representatives are said to have grown more receptive to offers in recent weeks, and Brazilian club Vasco have continued to explore whether a transfer might still be possible, driven in part by strong public backing from supporters keen to see the forward return to Rio de Janeiro.
Richarlison's Tottenham career has been in steady decline since a bright start following his move from Everton, with injuries and inconsistent form limiting his impact in recent seasons.
The club's insistence on a permanent exit, rather than a loan that would allow them to retain some control over his future, suggests Tottenham see little prospect of him featuring for the first team again and want to clear him from the wage bill entirely rather than continue paying his salary while he plays elsewhere.
With his exclusion from the domestic squad list already confirmed, any move before the market reopens in January would need to be agreed with a club outside the Premier League, leaving Vasco or another interested party as his most realistic route back into regular football before the turn of the year.
The relatively modest €20 million valuation reflects both his advancing age and his diminished market value after a frustrating spell in north London, but it also makes any deal more achievable for a Brazilian club working with considerably smaller budgets than those typical of the Premier League.
Whether Vasco or another Brazilian side ultimately meets that price remains to be seen, but Tottenham's clear preference for a permanent sale over a loan suggests the club has no intention of keeping the door open for a potential return.
