The Reds last claim the English elite league trophy in 1990. They went close to ending the title drought in 2002, 2009 and 2014 but emerged as runners-up on all occasions.
The Egypt international had been previously linked with Los Blancos in the past and the 41-year-old has stated that the desire to win a trophy could lure the 26-year-old away from the club.
“There’s always that risk [of players wanting to leave],” Heskey told the Express.
However, the former England international believes that the cordial relationship between the Reds’ fans and the players will want to motivate Salah along with his strike partners Sadio Mane and Roberto Firmino to continue on the Merseyside.
“The relationship between the players and the Liverpool fans is such that they always want to give the league another go,” he added.
“I’m not saying that they [Salah, Roberto Firmino and Sadio Mane] wouldn’t go, but there is plenty of reason for them to stay.”
Salah who has 16 league goals this season will hope to help his side return to winning ways when they take on Bournemouth on Saturday.
