Jurgen Klopp's men have faced Porto four times since the 2017/18 season, drawing them in the Round of 16 and Quarter Finals of the Champions League.
Liverpool have come out victors of both knockout rounds, scoring 11 goals and only conceding one.
However, Jurgen Klopp does not think it will be a similar outcome and his side won't be thinking back to them victories.
"When we came here last time we didn't think about the 5-1 game before. We are good but they are a top side - they qualify year in, year out for the UCL. They are a top team and that is what we are preparing for.
"This is a tough group and we should not waste time to get as many points as possible. We watched Atletico vs Porto and if one team deserved to win that game, it was Porto, that says a lot. That's the team we face tomorrow."
The German manager also went on to reiterate that Porto are a very good team and they've done some great recruiting since we last played them.
"Same manager but Porto have had players coming out and in. It's not an advantage to have won the last two games there. We think about this game and they have different opportunities to set up and we have to prepare for that.
"They have different options and we have to be ready for that. We cannot do shape tomorrow morning so we have to do everything today and make sure we are ready for tomorrow.
"We are often enough in this competition to know we can't win a game before we play so that is it."
Curtis Jones had a great game against Brentford at the weekend and he may be in contention to start in Portugal tomorrow, Klopp had this to say about the youngster.
"The Brentford game was a really good example of how he needs to play, defensively he was really good. He was involved offensively, he scored a wonderful goal. In midfield it's a rare moment when they're all fit - I have to make decisions.
"Even when you are good in training, you need to be especially good to be one of the three who will start. Performances like the last one help for sure for him to get game time."
Finally, Klopp confirmed that there is no new injury concerns going into the Porto game.
"Apart from the longer term injuries, they are all in. No Thiago, no Harvey - the rest are available. There are no new concerns at the moment. A big squad will travel. 23 are with us."
Naby Keita is also back in full training and it set to travel to Portugal with the squad.
