Klopp has seen the Scottish football improve in recent years.
He said, "I think it increased a lot.
"Yeah, Rangers and Celtic are obviously the standout teams in the league – that's no news – but I understand the best information you can get is how do they do in Europe. And Rangers' run last year in the Europa League was exceptional. I saw the games against Dortmund, for example, it was just really good. Especially with a home game, you can see how atmosphere can give you really the edge in a game and that was really impressive. And Celtic is obviously doing really well as well.
"You're right, the Scottish team is full of talent. We have, with Calvin [Ramsay], another Scottish boy here who's only back from injury and in the U18s another big talent. It's cool, it's a cool place to scout again if you want. I think it's a good sign for Scottish football.
"They might be a bit disappointed that they are not still in Scotland but, to be honest, with these two teams that dominant, we all know that if a player's really developing, it's probably not unlikely that he will at least give it a try in the Premier League or wherever. But it's, for sure, a much better moment than maybe four, five years ago and that's down to the players you have."
On Rangers, he added: "Good football team, well coached, exceptional European season last year obviously. Qualifying for the Champions League a big, big, big, big achievement. [I] saw obviously the last game against Hearts. I saw more games but now especially the last one. Really good football team and that's what we have to prepare for. And a team who have had results they didn't want, so that's what they want to change definitely. So, we expect a proper fight, a real fight, to be honest, and that's what we prepare for."
