According to Brazil's Globo Esporte, Vasco have contacted Richarlison's representatives and are considering a loan move for the forward.

Vasco want to understand Richarlison's current situation and whether he is willing to return to Brazilian football.
Richarlison expressed his desire to leave to Tottenham's management and head coach De Zerbi, after which his relationship with the club became tense. He was not included in Tottenham's Premier League registration list and is not part of the team's plans for the remainder of the season.
In recent days, Vasco fans have actively called on the club to sign Richarlison on social media. Richarlison is still training with Tottenham to maintain his fitness while waiting for his future destination to be decided. He does not want to remain without playing for a long period and is willing to consider various options.
Richarlison's contract with Tottenham expires in June 2027, and he can sign a pre-contract agreement with other clubs from December.
The major European transfer windows have closed, leaving Richarlison's team with fewer options. Richarlison had previously agreed on salary terms with Trabzonspor, but the two clubs failed to reach an agreement on the transfer fee before the Turkish transfer window closed last Friday. At present, Richarlison's team is prioritizing a move to the Saudi Pro League.
Richarlison has publicly stated that he is a Vasco fan, which also encouraged Vasco supporters' actions on social media. Pedrinho greatly admires Richarlison and had asked about the possibility of a loan move several times in previous seasons, but the response had always been that the player would stay at Tottenham.
With most transfer windows closed and Tottenham making it clear that Richarlison is not in their plans, the player's team is no longer ruling out a return to Brazil. Vasco are strengthening their attack and believe Richarlison could improve the team's quality.
