Asked when the pair could make their debuts, Klopp said: "We don't live in an ideal world and that means we have to be smart, we have to be quick.
"There are different things we can try to do to help them but obviously we play different to Preston and Schalke.
"They will need time but we don't have lots of it, so we will use the time we have in our hands and try our best
"If they had to start together tomorrow night, I think that would be not too cool. We will give them a few more days."
"We don't need to watch a Hollywood movie to see these kind of stories, in football it is possible as well," said Klopp.
"Yesterday Preston, today Liverpool. That is a nice story and I really can't wait to start working with the boys.
"I am a big fan of chances and giving opportunities. This is an absolute chance for the club, for us as a team and for the boys as well. It's great - let's go for it."
