The first half in particular impressed Klopp, who insists that it is the best pressing game he has seen.
"When my team get going, then this job is such a pleasure," Klopp told reporters. "The first half was truly exceptional.
"I'm absolutely delighted with our first 44 minutes. You just can't play a better pressing game than that."
Dortmund face Marseille in the Champions League on Tuesday night, although Klopp will be serving a touchline ban.
