Speaking to LiverpoolFC.com, Klopp said: “To be 100 per cent honest, it was not that I had a group I wished for or whatever. I expected a difficult group, we have a difficult group and that's what the Champions League is all about.
“PSG are one of the most exciting teams in the world and I think their target is to win the Champions League, so that will be two interesting matches.
“Napoli, we beat them in pre-season but it goes without saying these two games will be completely a different challenge.
“I've been to Napoli with Dortmund, so I know what the atmosphere is like there. In fact, it's where I got a suspension [for being sent off]. I can do better, obviously! Red Star, I watched them last night. They came through and it will be, again, a very, very intense atmosphere I am sure.
“But that's how it is, it's the group and I am fine with that. Now let's go.”
The Reds reached the final of the competition last, but Klopp insists the club are not looking at the past.
“Yes, but last season is last season and now we have to do it again. That's normal. All the teams have to do it again,” he said. “We want to go through the group. It will be difficult but still, we want to go through. That's the plan, so now let's start working on it.”
