Everton are reportedly set to let Allan leave the club this summer, as Frank Lampard is preparing an overhaul of his squad.
The 31-year-old has featured in 23 of their 28 Premier League games this season, and he has a contract at Goodison Park for another year.
According to The Sun, Allan is one of several players that could end up departing Everton during the upcoming transfer window, as Lampard wants to put his own stamp on the club.
The Brazilian international originally joined back in 2020 from Napoli, but the focus for the former Chelsea boss could be on signing Donny van de Beek permanently instead.
It has previously been reported that Everton could end up selling either Dominic Calvert-Lewin or Richarlison as well, with concerns about the finances of the football club.
Right now the Toffees are currently 17th in the Premier League, just three points above the relegation zone with the focus of the squad being on surviving this season.
