The Reds finished on 97 points, one point behind City, who went on to win the English top flight trophy for the second time in a row.
The loss means the Anfield outfit will now continue their wait for the Premier League title, having last won it in 1990.
Salah claimed his second consecutive Golden Boot award, sharing it with teammate Sadio Mane and Arsenal’s Pierre-Emerick Aubameyang, after they finished level on 22 goals.
The 26-year-old attacker has taken to social media to reflect on the 2018/19 season.
“It feels bittersweet now but the season isn’t over,” Salah posted on Instagram.
“I want to say thank you to my teammates, coaches, and to the fans. And fans, please bring Anfield to Madrid.”
Salah has scored 26 goals in 51 appearances across all competitions this season.
The Pharaohs are in Group A along with DR Congo, Uganda and Zimbabwe.
