Klopp won the German title twice with Dortmund in 2011 and 2012 with a youthful side that upset powerhouse Bayern Munich.
"It's a really exciting team. It reminds me a little bit of my team at Dortmund years back," he said.
"They were really young and people always spoke about that, but they only played because they were that good.
"Chelsea brought in (Christian) Pulisic in the summer, I don't know about the money but it was £50-60million? All the players around him now have the same value. Tammy Abraham is a £60m player, Mason Mount for sure is £60m, maybe more. Hudson-Odoi was already that. Jorginho is still young, Kante looks like he could play for the next 20 years, Kovacic, Barkley, then the experienced guys around them, Pedro, Willian, Giroud.
"If there was one club in the world where a transfer ban didn't hit that bad, it was probably Chelsea because of the transfer policy in the last few years with these players on loan. High-quality players.
"Abraham didn't learn where the goal is at Chelsea, he found it in different places. They are just a good team, they have all my respect. They are a proper contender for everything. Now we play there and we want to get something."
