It was the first time Spurs have failed to score in an away game this season and wingers Gareth Bale and Aaron Lennon were rarely seen, marked out of contention in a tactical triumph for QPR boss Harry Redknapp against his former team.
Villas-Boas was hoping Tottenham would be in a position to take advantage of any ground lost by their rivals in Sunday's matches at Old Trafford and the Emirates Stadium but QPR proved uncompromising opposition.
He said: "Obviously we wanted to win to make sure we profit fully from the weekend's games.
"Our away form has been excellent and we wanted to come here and win and we feel very comfortable away from home - after their win against Chelsea it was important to try and get the first goal and unlock them in some way.
"It is difficult to break them down and only if you score is it possible to find more spaces."
Redknapp confirmed he was looking at signing Spurs midfielder Jake Livermore.
The 23-year-old England international has struggled to break into the Tottenham side on a regular basis and his former boss wants to take him to Loftus Road.
"Livermore, yes. We are doing a deal to take Jake on loan," he said. "I like Jake, I'm a big fan of Jake's. He is a good young player and it will be a good experience for him."
However, Villas-Boas had a different take on the potential deal for Livermore and added: "There is nothing confirmed yet. I think when we announce it it will have to be official from all three parties."
