If an offer in the neighborhood of £60 million is received, owners FSG will consider a surprise sale.
Real Madrid, a powerhouse in LaLiga, is one among the teams keeping an eye on Salah’s precarious condition.
Liverpool cashed in on the Senegal star, who had only one year remaining on his contract, by selling Mane to Bayern Munich for £35 million this week.
The Egyptian hitman for the Reds, who is free to leave next summer, is starting to play out in a similar manner.
Salah, 30, and the club have been unable to agree on a new contract due to his desire for £400,000 a week in pay.
Liverpool would ideally like to keep the 31-goal leader from last season, but they won’t compromise their wage structure to do so.
Salah claims he does not want “crazy” money to stay because he makes slightly less money per week than top earner Virgil van Dijk, who earns £240,000.
Despite the animosity between Salah and Real stars stemming from two Champions League final fights in the previous five seasons, Real are keeping an eye on developments and would be able to offer a massive deal.
Before Kylian Mbappe decided to sign a new contract with Paris Saint-Germain, Bernabeu manager Carlo Ancelotti thought the France striker would be joining.
Real believed they would have to wait another year to sign Salah, but Liverpool’s attitude has hardened after they paid Darwin Nunez what may have been a club record £85.3 million.
While Fabio Carvalho, who recently joined from Fulham, has a commitment worth £7.7 million, Luis Diaz was signed in January for a potential total cost of £49 million.
Back-ups are also being attacked by teenagers Harvey Elliott and Kaide Gordon.
Liverpool is aware that keeping Salah would represent a significant financial risk in their quest to win back the championship.
Although they would refuse to sell to a Premier League rival, Americans FSG are renowned for being careful with the club’s finances and may decide to take the money and run.
