Klopp is expecting a thriller at Anfield.
Liverpool have won the last three matches against Guardiola's team.
The German is expecting his Reds to host a strong City side that will fight really hard at Anfield.
"In the 4-3 [game], they were really good and they won before that 60 or 70 games in a row, or that is how it felt.
"They never gave up, even when they were 4-1 down and that made them really special last year.
"I expect them to be like this again. They are really going for results.
"Last year we won the last three games against City, twice in the Champions League and once in the league.
"After these game you don't go into the dressing room and think: 'Now we have got it. Now we know how to beat City' because there is no real way or one thing that you have to do.
"You have to be ready and have a fantastic football team. Thankfully I have that with outstanding character, ready to be brave and ready to make mistakes in a very difficult game against an outstanding opponent.
"It can work. That is all we need to know.
"When somebody says to me: 'Good luck for Sunday', I think unfortunately we need it."
