Liverpool have now scored 26 goals against Arsenal since Jurgen Klopp took over in October 2015.

There have been more one-sided affairs than this, but at this stage of the campaign it was a showing of remarkable physical strength.

“It was a brilliant game from my side so early in the season,” said a beaming Klopp.

“It was outstanding. It was a performance full of power, energy, greed and passion, which I think you need to have against a team like Arsenal.

We were completely in charge of the game. We are not Disneyland, we do not need to excite everyone in every second. Our identity is intensity, and we showed that today.”

It was hard to know what was more frustrating for Emery: the defensive collapse or the wasted opportunities in the first half.

Arsenal had their chances in those opening exchanges, causing plenty of problems through the speed of Pierre-Emerick Aubameyang and Nicolas Pepe, but their hope dwindled with every wayward shot and tame finish.

Was it an improvement on last year’s 5-1 thrashing here? Certainly. Was it enough of an improvement to make them think they are ready to seriously challenge sides like Liverpool and Manchester City? Absolutely not.

Arsenal remain worryingly frail under pressure, with Luiz’s addition seemingly doing little to paper over last season’s cracks.The Telegraph
