But they have rediscovered their scoring and winning touch, defeating Tottenham and West Ham United this week.
Asked if they can challenge for the title they won last term, Salah told Sky Sports: "Every year is like that. If you want to win the league, you have to win every game.
"But this year City were struggling in the beginning and now we were struggling three or four games ago.
"You just need to keep winning if you want to really win the Premier League."
