Liverpool returned to the top of the Premier League table with a narrow 1-0 win over Burnley on Sunday.
The Reds lost their spot a day before, following Arsenal’s emphatic 3-0 victory over Nottingham Forest.
For most of the game at Turf Moor, it appeared that Arne Slot’s men would not be able to find a way past their stubborn hosts.
The champions failed to score from 26 shots with around 80% possession.
Hannibah Mejbri’s handball in stoppage time gave Mohamed Salah the chance to strike a late spot kick.
After Lesley Ugochukwu’s red card for two bookings, former Manchester United midfielder Hannibal raised his hands needlessly in the area to block a cross, leaving referee Michael Oliver no choice but to point to the spot.
The result means Liverpool maintains their perfect start to this campaign with 12 points from four fixtures.
