Spurs won 2-0 on Saturday employing Frank's high pressing game.
During his time at Brentford, he often used the same type of aggressive pressing. But this is the first time he has openly said that Klopp has been a direct source of inspiration.
"He's a smart man. I have to send him a text message," said Frank.
"I definitely believe in the aggressive pressing, which you saw today and which you saw with my Brentford team. I believe in high pressing, I believe in being on the front foot. I like that mentality."
Frank continued: "I think it's offensive, it's a more offensive way to defend and it's more fun to defend in the opponent's half of the field.
"Today I think we were very successful, we also scored a goal thanks to that."
