The European champion put three goals past promoted Norwich City in the opening half hour at Anfield on its way to a 4-1 victory and any concerns Liverpool fans may have had about the lack of transfer activity surely had vanished by the break.
The weeks of speculation and debate that surround the transfer window can have a distorting effect when evaluating the strengths and weaknesses of Premier League teams.
Why, asked some pundits, had Liverpool not spent some money to add some fresh alternatives to its attacking trio of Mohamed Salah, Roberto Firmino and Sadio Mane?
Klopp could not care less about such criticism and his decision to start Divock Origi ahead of Mane showed he has real belief in the Belgian to be a significant factor this campaign.
“We made the decisions we made (in the transfer market) for the reasons we had. I think Div (Origi) did exceptionally well tonight,” said the German.
“He made two or three decisions that were not too good and lost the ball here and there, but until then he was really brilliant. He was a proper threat all the time,” said Klopp.
“We are early in the season and some mistakes happen that will not happen during the season. But it’s all good.
“If somebody would have told me before the game we would win 4-1, I would have taken it easily. If somebody would have told me we’d play the first 60 minutes like we played tonight, I’d say, ‘OK, I take it.’
As for questions over options, it was enough to take a look at the Liverpool bench — Joel Matip, Naby Keita and Xherdan Shaqiri were unused along with Alex Oxlade-Chamberlain, back after his lengthy injury absence.
Midfielder James Milner and Mane, the league’s joint top scorer last season on 22 goals along with Salah and Arsenal’s Pierre-Emerick Aubameyang, made second half appearances.
With Wednesday’s UEFA Super Cup match against Chelsea in Istanbul followed by a trip to Southampton in the league on Saturday, Klopp already knows he has to rotate his players.
“The players had a break (over the summer). For the body it was long enough, nobody asked for longer, so they didn’t lose a lot of their physical standards,” said Klopp.
“We have to be a bit smart for the next two games, we have to make a few decisions and try to win both of those games, which will be difficult.”
Liverpool’s Brazil keeper Alisson Becker is out of Wednesday’s clash with Chelsea — and could face a longer lay off — after suffering a calf injury during victory over Norwich City.
Becker went down in the 36th minute, slipping as he was playing the ball out and called for medical attention.
A stretcher was brought out but he was able to leave the field with the help of support staff.
“It’s a calf injury. He felt as if something hit him from the back. He won’t be ready for Wednesday, I can say that already,” said Klopp.
“It is not good but we will find a solution and move on,” added the German.
“We have to see how serious it is and then we have to deal with it. It’s the calf and that’s it. He couldn’t carry on, that’s not a good sign. We have to see,” he said.
“Wednesday (in the Super Cup), he will not play – with all my experience, I can say that already. He is injured, for sure, so we have to see how much.”
