The Reds face the Spanish giants in the first leg of the Champions League quarter-finals tonight (06.04.21) as the sides go head-to-head for the first time since meeting in the 2018 final, in which Real won 3-1 as Mohamed Salah was injured after a controversial challenge from Sergio Ramos.
Klopp insists that his team are only motivated by the present rather than looking to bury ghosts of the past.
He said: "My motivation is at the highest level, we play Real Madrid in the Champions League to get to the next round, it's not because of 2018.
"But when we get the draw and I see we face them for the first time since then, of course I remember the game. I said it at the time, if someone asked me a week after the game if I would invite Sergio Ramos to my birthday, I would say no. Meanwhile, I would think about it again now.
"I did not like what happened that night, it was a strange night, but it was long ago. I cannot get that feeling back, that anger or whatever, so I don't even try."
Klopp continued: "We are not on a revenge tour here. Life is like this, you try everything to win a game, you lose it and then you meet your opponent again one day.
"Sometimes it's close enough and you can meet a week or two later and have this kind of emotion still in you.
"I don't believe too much in revenge but it would be nice to get through against Real Madrid because that would mean we are in the next round and that's what we actually want to do."
