Salah finished the season with 23 goals, sharing the Golden Boot with Tottenham forward Heung-min Son.
The 29-year-old becomes the seventh men’s player to win the award twice, after being honoured in 2017-18, joining Mark Hughes, Alan Shearer, Thierry Henry, Gareth Bale, Cristiano Ronaldo and De Bruyne.
Salah said: “It’s a great honour to win a trophy, individual or collective and this one is big so, very happy and very proud of that. This one is a really good one to win, especially because it’s voted by players.
“It shows you that you’ve worked really hard and you get what you worked for. I have my room with trophies in a cabinet and I made sure that I had another space for one more. I always keep space and just try to imagine that the trophies are going to come.”
He added: “When you get older, you feel like you’re more stable and you know exactly what you want from football so I’m just trying to really chill and help the team. That’s why I think I also won the playmaker because it’s like you’re more aware of the game, so you just try to make the people next to you better and try to make yourself better as well.”
