The Dane insists there's no reason to rip up the foundations laid by the Australian, who was sacked despite leading the club to victory in the Europe League.
"First and foremost, I think it's important to say that, Ange and his staff achieved massively by winning the Europa League title," Frank told Men in Blazers. "Fantastic.
"First time in 41 years, a European title. I love that. I thought it was a lot of good things that I can use and I can, you know, stand on that foundation and then build from there.
"What I like to add is probably a bit more balance in my view.
"Attacking, defending. and then, of course, I think if you want to achieve something big, we need to be be good in all phases of the game."
Frank was also asked about the future of club captain Heung-min Son.
He added, "I think first and foremost, Son's legacy here is remarkable. He's been a fantastic player for Tottenham, he is a fantastic player for Tottenham.
"I see a player that that can play a very good role here next season. He's come in, very good mindset, trained very hard, pushed the players. So I'm excited about it."
