After an inconsistent first five months in charge at Spurs, Frank is seeking further improvements to the squad he inherited.
"After the window shut in September, we had the first formal meeting and it is an ongoing process that I, of course, also get to know more and more (about) the squad and players,” Frank said.
“One thing is the daily interaction and I have also seen a lot of games live, watched them back and you see all the small good habits and bad habits from the players. What can you affect? Or (what) will be tricky? Or how the relationship is?
“That knowledge gets us closer and closer to knowing what we want.”
Frank continued: “Of course. We will definitely be in the market. No doubt about that.
“We want them as early as possible, like every other time and let’s see if we can have them before the 31st of January."
On Spurs’ failed attempts to land Ebere Eze, now of Arsenal, and Nottingham Forest's Morgan Gibbs-White, Frank insists it didn't knock them off their stride.
“I am very happy with the players I have,” he said.
“If I ever speak about other players, it needs to be (Lionel) Messi or (Cristiano) Ronaldo, (who) are retiring soon.
“I think not about that specific situation or other players, just every position we have, we have more players on the list for right-back, centre-back, number six, goalkeeper, right winger, whatever... and it is never straight forward in terms of signing players, that’s for sure.”
