Spurs travel to Reading on Sunday seeking their first win of the season, after accumulating just two points from their first three games, but Walker has insisted that it is only a matter of time before the north London side hit form, and says everyone is pulling together in the right direction despite some disappointing results.
Although Villas-Boas has won just three of his last 15 games in the top-flight, Walker is adamant the 34-year-old former Porto and Chelsea manager is on the right track and that the tide will soon turn.
"The gaffer has been top-class tactically, and training-wise it's the hardest I can ever remember in my career," Walker told reporters.
"Results may not have come but it takes time to gel. Personally, I don't feel any pressure. If you feel pressure in football, you're not going to play your best. Once we put into practice what we are working on in training, we could go out and beat someone 6-0. I'm certain it will come good."
Walker has described Villas-Boas as a breath of fresh air at the club, and believes Tottenham are moving in the right direction with him at the helm.
"I was excited when he got the job. Chelsea are Chelsea; Spurs are Spurs.
"There has been no bickering whatsoever. The gaffer before was very old school but it's modern-day football now. It's fast, it's quick, the tempo is frightening."
Walker also revealed how fellow England full-back and Chelsea defender Ashley Cole praised the managerial quality of Villas-Boas, despite his ill-fated spell at Stamford Bridge: "Ashley had nothing but positive things to say about him.
"I remember playing against Ashley when the gaffer was at Chelsea. He was incredibly difficult to mark because of the way the gaffer gets his full-backs playing.
"Jose Mourinho was known as the special one - maybe he learned from him," he added.
