Liverpool boss Jurgen Klopp admits he doesn't know if he and Pep Guardiola like eachother.

Liverpool host Guardiola's Manchester City tomorrow.

"I don't know 100% if we like each other, I just know the respect is there," Klopp said. "We have had talks, phone calls, stuff like that in different moments. He went through a difficult period. I went through a difficult period. On a private basis. So we had contact there.

"I can't say nothing about old rivalries. I don't know. Sir Alex Ferguson I know a little bit. Respect him and like him a lot but we met five times in my life. Arsene Wenger more often because we played against one another. Rafa Benitez I don't know.

"Jose Mourinho? I am pretty sure on a private basis he's a good guy but how can you have with him a good relationship? It's like 'Jose sit down'. It's tricky. But during the games we are rivals and it's normal.

"It's just respect. It's not easy to respect what we are doing here as well. It's how you can have a relationship without having a relationship. While we are in charge of our respective clubs, why should we have a friendship or relationship?

"After that if we meet and look back then there will be a lot of things we could share and that will probably happen. But that will have to be after and I don't know when that will happen."
