Klopp is preparing to take charge of his first Liverpool game against Spurs on Saturday, and he is expecting a tough test.
The German manager says that, despite the Lilywhites' current injury problems, they are a team with a lot of quality, and he can tell that they have been playing together for some time.
"We are playing against a very, very good Premier League team," he admitted. "They work together for some time. They look fine-tuned, and they look very good together.
"Maybe they have some problems with injuries, but they are a very good team."
Mauricio Pochettino opted to keep the bulk of Tottenham's squad together over the summer, with only a few tweaks made to their starting line-up.
This stability has paid dividends so far, and Spurs have pieced together a very impressive start to the new campaign, going unbeaten in the league since the opening day.
Their match against Liverpool will be a tough one though, as so much momentum is behind Liverpool following the appointment of Klopp.
The former Borussia Dortmund manager has been the centre of attention since his arrival in England, and he will be keen to get off to the perfect start, ensuring that the optimism around Anfield isn't deflated.
