Liverpool and Chelsea maintained their perfect Premier League starts after four games on Saturday as champions Manchester City edged past Newcastle to remain two points behind the early leaders.
A huge error from £65 million ($84 million) goalkeeper Alisson Becker threatened to halt Liverpool's early season charge, but Jurgen Klopp's men held out for a 2-1 win at the King Power in another demonstration of their new-found defensive solidity to go with the firepower of Sadio Mane, Roberto Firmino and Mohamed Salah.
Chelsea had to wait until 19 minutes from time to break down Bournemouth at Stamford Bridge before the in-form Pedro Rodriguez opened the scoring and Eden Hazard sealed the points in a 2-0 win.
City bounced back from a rare slip-up at Wolves last weekend thanks to goals from England internationals Raheem Sterling and Kyle Walker in a 2-1 success to celebrate the 10th anniversary of Sheikh Mansour's takeover that has transformed the club.
At the other end of the table it was another afternoon to forget for West Ham, who remain the only Premier League side without a point, as Adama Traore snatched a 1-0 win for Wolves in stoppage time at the London Stadium.
On a rare off day for Salah, who was substituted 20 minutes from time, Mane and Firmino stepped into the breach to give Liverpool a 2-0 half-time lead at Leicester.
But that was a more comfortable cushion than they deserved as for the third straight game the Reds failed to produce their free-flowing best.
Alisson more than played his part in registering clean sheets against West Ham, Crystal Palace and Brighton, but the Brazilian number one was caught trying to dribble past Kelechi Iheanacho and the Nigerian squared for Rachid Ghezzal to set up a grandstand finish.
"It's only positive that he is that good a footballer. But we all have to learn to use it in the right way still," said Klopp of Alisson's propensity to take risks.
