The German's side have won two Champions League matches either side of a draw at home to Brighton but results prior to that were inconsistent at best.
Klopp deviated from his established 4-3-3 to play 4-2-3-1 in Tuesday's 2-0 victory over Rangers after accepting prior to the match he had to find a solution to Liverpool's issues.
But Klopp insists it was not because opponents had finally discovered ways to expose his tried-and-tested methods as that happened years ago, it was just his team was playing so well they could not effectively implement their plans.
"For us it is much more important for us that we become unpredictable again and we need different systems for that," he said ahead of Sunday's trip to Premier League leaders Arsenal.
"It is not the only system we can play: is it 4-4-2, is it 4-3-3 or is it 4-5-1, 4-4-2 or 4-2-3-1?
"We don't want to make it more complicated than it is but there are obviously different systems available for us and we have to choose which one is the best for the next opponent or the best for us in the moment. We have to be more unpredictable, definitely."
On his tactics being 'found out', Klopp added: "Teams worked out how they can play against us when we are not at our best.
"Other teams have worked out how to play against us for years but it didn't work out for them because we were exceptional.
"In our best games I could show you the parts where we had problems and in the moments when you don't play on your top (level) these gaps are still there.
"There is no system in the world with no weakness: five at the back, four, three, no one, it is all about how we perform.
"If you look at it you know where the gaps are but you fill it with your movement or are only open for a minute and then you close it."
On the reason for wanting to be more unpredictable Klopp said he just wanted to give opponents something else to think about and it was not about improving offensively or defensively.
"If you prepare for (playing) us it makes sense that you just have to think twice or three times where there might be something you could use," he said.
"For us both things are important, defensively being compact and offensively having different players in different positions. Both make sense."
