Spurs won thanks to a brace from Micky van de Ven and Pape Matar Sarr. The result takes Spurs into third place on the Premier League table.
Frank said afterwards: "Very, very happy with that, I think we were all very solid performance, especially pleased with the first half. I think we were good in phase one, good in phase two. More passes, control of the game, more in phases. In general, the second half was a little bit more of a dogfight at times.
"Going here to Everton, which is against a very good team, well set up by David Moyes and a very good home crowd, they've been unbeaten here so far. To any ground in the Premier League, to win 3-0 away from home is a very good result. So, yeah, very happy, happy with obviously the set pieces as well. What I would say, the clean sheet mentality, that is a very good foundation to stand on.
"That gives you an ability to perform at a certain level where you want to always do a little bit more, but be really, how can you say, competitive and especially away from home. And then I think we are, is it three years ago we played Champions League, or three years ago? but it's still quite an inexperienced Champions League squad to go every third or fourth day. And one of the most difficult things with that is to be able to compete in both tournaments and especially after an away trip in Champions League and then go away in the Premier League again.
"So to keep the energy, the focus, the intensity to be able to do that, I'm very pleased with the players, how they handled that to get the win today. Plus, we also did it after Boulogne, travel, then travel to Leeds and win. So I think it shows a lot about that mentality. There's things we like to work on, but the most important thing is the mentality."
On two-goal Van de Ven, Frank also stated: "First and foremost, I think he's really growing and taking some big steps. I'm very pleased with him overall. I think he's taking more leadership. I think he's defending better and better, not only using his pace but also more clever positions. I'm very happy with that.
"And then I said, actually at the beginning of the season, I said, it's OK you score with your left foot and your right foot, but you need to score more goals with your head. You're centre- back. And then we have worked with it and that's a big praise to Micky, but especially to Andreas (Georgson, coach) and the way he, how can you say, attack the ball, also get in there where it hurts, I think is key. Now, yeah, hopefully it will continue."
