Frank oversaw victory in Tottenham's first friendly of their preseason, with Will Lankshear and Luka Vuskovic, on debut, the goalscorers.
The Spurs manager remarked afterwards: "I thought there were a lot of positives in there.
"If we start with (Mohammed) Kudus, of course, he’s the newest one. He was exciting to watch. He had four, five very good actions where you could see what he’s about. His pace, one-on-one skills, the way he can twist and turn going forward.
"That was a positive. There were a lot of others where I get to know them better. I’ve watched them a lot over the years, before I got appointed. But this - when you see them here now and when I watch the game back - are all the details we can go through."
On Vuskovic, he continued: "Luka deserves the praise as well. A great header. Showed his physicality and his composure on the ball. He’s not getting stressed when opponents get close. And what a strike.
"He's amazing, young, lots of confidence and you can just see his presence on the pitch and I think it's a good thing today that he's got his goal and assist."
