Jurgen Klopp believes their Champions League trip to Porto will be a test for his team as they seek to make it two wins from two.
The Reds won their first match of the group stage against AC Milan in a pulsating 3-2 win at Anfield.
Klopp eyeing Reds response
There was disappointment for Klopp's men at the weekend as they twice let a lead slip to draw 3-3 away at Brentford.
Goalscoring has been no issue for them this season with some of their attacking play reminiscent of their title romp in 2020.
However, defensively there were lapses against Brentford which were also highlighted in the Milan contest.
They face a Porto side who drew 0-0 with Atletico Madrid in the opening group stage encounter in this year's Champions League.
Klopp wary of unpredictable Porto
Liverpool's recent record against Porto is good, with the Reds winning three of their last four Champions League matches, including a pair of wins in April 2019 on their way to a sixth European success.
However, Klopp does not want to dwell on the past says the upcoming challenge will be a difficult one.
"Porto always change a little bit, they've had players going out and in, still the same manager," said the German.
"It's not an advantage at all that we won the last two games because the opponent will not want the same thing to happen again so it makes it not an easier job for us.
"But we don't think about the last two games we think about this game, they have different opportunities to set up their line-up and system and we have to prepare for that."
