Liverpool manager Jurgen Klopp has admitted that his team "switched off the machines" after going 4-1 ahead at Arsenal.
The Reds had to withstand a late fightback from the Gunners before winning 4-3 at the Emirates Stadium and beginning their Premier League campaign with three points.
Klopp also suggested that his celebration after Sadio Mane's fizzing strike may have played a part in Liverpool's mini-slump.
He is quoted by BBC Sport as saying: "At this moment, we switched off the machines. The game was not over. Arsenal lost, but we gave them a path back into the game.
"Nothing is sure until the final whistle. Over the whole of the 90 minutes it was a deserved win.
"We can always score goals and we can defend much better. It's the Premier League and nothing should be easy in this league. Nothing is easy."
Liverpool have now scored 45 goals in 2016, more than any other team this calendar year.
