The 52-year-old was speaking after returning to Brentford for the first time since leaving the club in the summer, a night that ended with frustration for Tottenham supporters following a goalless draw and another subdued attacking performance. Spurs fans voiced their displeasure with chants of "boring" during the match, followed by boos at full-time.

Asked ahead of Sunday's home game against Sunderland whether he was enjoying the task at Tottenham, Frank was honest in his response.

"That's a good question," he said with a laugh. "When you need to put in a big, big shift and it's not smooth and it's tough, it's probably difficult to enjoy it.

"If I run hard, I don't enjoy that moment, but I know I need to keep my head down and run hard to get through it. We are in a situation where we need to run hard to stay in it and get through it."

Frank believes the current struggle will prove valuable in the long run, describing the period as an important learning curve.

"When we look back on this spell, maybe this first year when it was tough, we'll think what a learning, what an experience. It will make us much better for the future," he said.

"So the short answer is no, but it's a privilege to be in charge of this fantastic club during a big transition. There have been huge changes at the top of the club, more than at any time in its history, but the potential is massive."

Tottenham have kept four clean sheets in their last six matches, including the draw at Brentford, but Frank acknowledged that a lack of attacking threat remains his biggest concern.

Injuries to Dominic Solanke and James Maddison have limited Spurs going forward, while Dejan Kulusevski has also struggled for fitness. Xavi Simons is currently suspended, adding to the problems.

"I knew it would be a big challenge," Frank said. "I didn't expect Solanke and Maddison to be out for seven months, or Kulusevski not to be ready, but I knew it was a transitional season.

"We are building something I am convinced will be very good. I know what needs improving, and I'm very aware of how to address it."
