Liverpool set out their stall for the Premier League season with a clinical opening half which ended with the reds 4-0 up.
Klopp stuck to the same team that he started last week's Community Shield with, and Divock Origi enjoyed his first appearance back at Anfield.
Sadio Mane - who returned to training on Monday - was named on the bench.
But there was no rush for the man for Senegal to come on the field. His replacement was doing just fine.
Origi forced the own goal that opened the reds scoring (an own goal slice) and ended the half putting away the reds fourth goal - Trent Alexander-Arnold supplying the cross.
Sandwiched between these was a Mo Salah/Firmino combo that saw the Egyptian slide the ball into the net and then Virgil van Dijk got his head on to the end of a Mo Salah corner to get his goals tally off to a good start.
There was worry in between the goals when Alisson Becker had to leave the field with a suspected calf strain. Hopefully nothing more serious although the talk post match was of an achilles injury which is likely to be far more serious and could result in a lengthy absence.
It did however provide brand new signing Adrian with a very early debut for his Liverpool career.
Norwich had more chances than the reds in the first half but the 4-0 scoreline summed up the difference in experience at this level of football.
Liverpool should have had more goals in a blistering 10 minute opening spell in the second half but Tim Krul constantly thwarted them and when Teemu Pukki lashed away his second half chance it was the least Norwich deserved.
The three points will be gleefully accepted but there were concerns at times, as there have been all pre-season, about Liverpool's defending.
So reliable last year, Joe Gomez and Trent Alexander-Arnold were both caught out of position on a number of occasions and there is clearly plenty of work still to do on the training field.
