Pressure is building on Frank, 52, following another disappointing result that now leaves Tottenham down in 11th with 22 points from their 16 games.
Spurs now have just one win in their last five Premier League games as they prepare for a visit from current champions Liverpool on Saturday (December 20).
Speaking after the game, Frank urged Spurs fans to give him more time to implement his ideas, insisting there is no “quick fix” to their current bad run of form.
Asked if he would be given time, the Dane said: "I can't see why not. I think it's pretty evident that if no one gets the time, no one can turn this around. This is not a quick fix.
"I do everything to control my emotions, which is a hurricane inside me, because, of course, it's deeply frustrating that we are not doing better today after three good performances," he said.
"I think it is extremely important to be calm and measured and of course, have very, very direct and clear messages at the right time, so they're not in doubt of what I think.
"I'm very honest about where we are as well. I was also very honest, today was a very bad performance, no two ways about that.
"But I also know that to change this will take some time. No one will want to hear about that. It's just reality.
"I think the ones who have followed the club and the team, I think it's fair to say there's been a few not too consistent performances and that's the thing. We are working very hard."
