The 31-year-old has been first-choice goalkeeper at Anfield ever since making the £68.8m switch from Serie A giants Roma during the summer of 2018.
Within his 263 competitive appearances for Liverpool, Alisson has managed to win the Premier League Golden Glove on two occasions and the best goalkeeper award in the 2018-19 Champions League.
As well as individual accolades, the former Internacional stopper was a cornerstone of the Reds' success under legendary head coach Jurgen Klopp, winning the Premier League and the Champions League.
Alisson has spent the summer on international duty at the Copa America in the United States, where Brazil were defeated on penalties in the quarter-finals to Marcelo Bielsa's Uruguay.
Liverpool 'braced' for massive Alisson offer
According to Football Insider, Liverpool are preparing for the possibility of Alisson's six-year stint at Anfield coming to an end this summer.
The report claims that Arne Slot's side are expecting a major bid from a team in the Saudi Pro League for the 69-time international, who has played for the Selecao over the past nine years.
It is understood that the club in question would offer Alisson a 'jaw-dropping salary', with the Pro League continuing their attempts to recruit some of European football's best talents.
Liverpool are said to be hoping to keep hold of Alisson this summer, with the Reds currently having no intentions of cashing in on the 31-year-old.
However, it is believed that the Brazilian's head could be turned by a lucrative financial offer from the Middle East, as the shot-stopper approaches the backend of his career.
Man City also at risk from Saudi raid?
Liverpool are not the only Premier League heavyweights who could be losing their first-choice keeper to the riches of Saudi Arabia this summer.
It has been reported that Manchester City have received a £25m offer from an unnamed Pro League outfit for six-time title winner Ederson.
The 30-year-old missed the Copa America with Brazil after fracturing an eye socket during a collision with Tottenham Hotspur's Cristian Romero in a match on May 14.
Stefan Ortega stepped up to the plate in Ederson's absence, but it is likely that Pep Guardiola will be desperate for his first choice to stick around for at least another season.
