The Egyptian retained the honour after half-a-dozen strikes in four appearances increased his overall league tally for 2017-18 to 29 as he chases the Golden Boot in his debut Reds campaign.
Salah opened the scoring in a 2-0 victory over Newcastle United, bagged four of Liverpool’s five – and set up the other – as Watford were thrashed at Anfield, and hit the winner against Crystal Palace on the final day of the month.
He claimed the accolade ahead of Romelu Lukaku, David Silva, Son Heung-min, Cenk Tosun and Chris Wood.
It is the first time a player has ever won the award three times in the same season.
