Jurgen Klopp insisted Liverpool produced a near perfect opening to their title quest.
But he revealed the night at Anfield was spoiled a little by one sour note, when keeper Alisson limped off in the first half with what he fears was a calf tear.
The Reds offered Norwich a harsh introduction to life back in the top flight, with a pulsating blitz in the first half, which simply blew them away – and posted an emphatic title notice from the Reds.
But Klopp revealed that his Brazilian keeper, who is an inspirational figure in this side, felt a stabbing pain in his calf when he slipped taking a goal kick. And asked if it was a tear, he replied:
“It’s probably more than a strain. We will have to see. It does not look too good.
“Good performance as a start, for a long part of the game, really good. Maybe it’s a tear but how can I say that without a scan?
“He is injured, but we don’t know how much. He couldn’t carry on, that’s not a good sign. So. With all my experience, I can say he won’t play Wednesday.”
That gives new signing Adrian, the former West ham keeper, a chance to play against Chelsea in the Super Cup final in Istanbul, and the manager explained that wouldn’t be a problem for the Spanish keeper.
Liverpool have a real problem because their two young keepers who are back up, Caoimhin Kelleher and Vitezslav Jaros are also both injured.
That may even see them apply for permission to bring in another keeper, but Klopp says Adrian is up to the task.
“Alisson looked behind him because he thought something hit him. But Adrian is a good goalie. In possession he is calm and he is good at shot-stopping, that’s why we signed him.
“It’s good for him but we have a little problem with Ali.”
If it is a calf tear, then it is likely to be an absence of one to three weeks for the keeper, though a grade three tear could take longer. The indications are though, that the injury will not prove debilitating.
An own goal from Norwich skipper Grant Hanley set the tone on the night, and inspired by Mo Salah and Roberto Firmino, Liverpool ran riot in the first half with four goals.
They could have doubled that tally after the break, but missed several chances and visiting keeper Tim Krul made several class saves, but Klopp was still happy despite a Norwich goal.
“We were really really good and for 60 minutes and did what we had to do – It’s all good, if somebody told me before the game we would win 4-1 I would take it, easy,” he said.
“And if they said we would play like we did for first 60 minutes, I’d definitely have taken that. “
Klopp also insisted his side’s focus is now on winning the title – and explained Liverpool didn’t parade the Champions’ League trophy before the game because they are looking forward, not back.
“Nobody told me I have to!” he said when asked why they didn’t bring the cup out. “I touched the European Cup on the (CL final) match day and the day after, since then not.
“We are now in the new season, and I don’t have to think about that any more.”
