The Reds are assured top spot in their group, essentially making the clash a dead rubber.
But Klopp wants the Anfield faithful to deliver another spine-tingling Champions League night.
"It will be a difficult game for us and I really hope that Anfield is at its best. It's the Champions League - you can never take it for granted. We need to be ready as a whole, all together, to put a proper fight out there.
"They were without their No 1 centre-half pairing, had an early injury in the game - all these things didn't help. We scored in the wrong moments for them, so it all came together.
"But we prepare for an incredibly strong Porto team tomorrow. They have a lot to play for.
"What we need here at Anfield is an exceptional atmosphere from the first second. If we want to win the game tomorrow, we can only win it together, and that's really important.
"I hope we can create this kind of atmosphere and then it will not be easy for Porto."
