Given the relentless pace being set by City at the top of the table, Liverpool couldn’t afford any slip ups at Turf Moor despite Jurgen Klopp making seven changes with Mohamed Salah and Roberto Firmino left on the bench and Sadio Mane missing through injury.
Their firepower was badly missed as Liverpool laboured in the first-half and went behind early in the second.
A huge error by £67 million ($75 million) goalkeeper Alisson Becker for Burnley’s shock opener when Jack Cork bundled home after the Brazilian fumbled in the wet conditions.
However, the visitors quickly rallied to stretch their unbeaten start to the league season to 15 games.
James Milner levelled just after the hour mark and then turned provider for Firmino to turn the game around just three minutes after coming on as a substitute before Xherdan Shaqiri sealed the three points late on.
“The character we showed after going behind, to come back in that fashion is what we expect from this team,” said Milner.

“Today was more the same, but with great spirit and people ready to have a go and fight hard, it was a credit to the team.”
Arsenal were barely done celebrating when the ball was in the net at the other end as a misunderstanding between Sead Kolasinac and Leno allowed Jesse Lingard to nip in and equalise.
De Gea redeemed himself with two fine saves from Pierre-Emerick Aubameyang and Henrikh Mkhitaryan also had a late Arsenal goal ruled out for offside.
Wolves registered their first win in seven games despite going behind to Ruben Loftus-Cheek’s 18th minute opener for Chelsea.
