Chelsea manager Thomas Tuchel has hailed Jurgen Klopp as a 'genius'.
Tuchel will come up against his compatriot when Chelsea travel to Liverpool on Thursday.
The German told a pre-match press conference: "Of course there are coaches here in the Premier League when you enter the competition with not only the best clubs but also the best coaches in the world, one of them is Jurgen, clearly, and he has proven that at many clubs.
"It brings me out of bed early because it is a challenge for me to play against him. He is a genius but in the end we will not meet up for a game of tennis, we play with our teams and we have to be prepared.
"Jurgen has proved to be outstanding, he transforms any club into a unit and, at all the three clubs he has worked at, he has been a big part of them, with the heart of the fans. He is a huge success."
Asked to address the similarities between himself and Klopp, the Chelsea boss added: "I'm pretty relaxed about all the comparisons, if there are comparisons between Jurgen and me. This is what we are up for clearly.
"It stays one of the toughest challenges to play at Anfield and we want to get the most out of it."
