Substitute Divock Origi scored in stoppage time to send Liverpool top of the table with a 1-0 victory over Wolverhampton Wanderers.
Liverpool created the most chances but were repelled for most of the match by a stubborn home side.
The best of the first half fell to Salah but Romain Saiss made a vital challenge to deny the Egyptian a tap-in.
Liverpool remained on top in the second half, with Thiago twice denied by goal-saving blocks before firing wide.
Then, with Jose Sa beaten, Diogo Jota’s shot was somehow kept out by a goalline block from Conor Coady.
Sa then kept out both Mane and Salah before, the fourth minute of time added on, Origi received Salah’s pass, spun and finished low.
A first defeat in four matches leaves Wolves eighth with 21 points.
Liverpool move above Chelsea with 34 points, but can be overtaken by Manchester City if they beat Watford.
