The Tottenham manager had been vocal about a lack of preparation time coming into the game with his team having played on Thursday and Sunday before travelling to Villa Park but his players showed no signs of tiredness as they romped into the fourth round.
And following their win Villas-Boas heaped praise on his squad for the way they brushed aside Paul Lambert's side.
"(It was) a good performance," the Portuguese manager told Sky Sports.
"And a great response from the team.
"We came here with three players that played that game (versus Cardiff on Sunday), which was a risk, but it was a great response from the team.
"We have great strength in depth, great team spirit this year and the players are all buzzing for opportunities like this."
"It was another super performance from Jermain Defoe," Villas-Boas said.
"He showed great desire, his performances have been excellent."
"Hopefully if we can get the calendar right (we can do well)," the 35-year-old said.
"Normally we would be given the opportunity to play on Wednesdays, if that happens we will be in contention.
"We want to go further (in the competition)."
