The manager has claimed that his side do not lack discipline after the two red cards and seven yellows they received, adding that he wants a better performance next time out
Jose Bosingwa and Didier Drogba were sent off in the game against Neil Warnock's men, while seven other Blues players were booked.
However, the Portuguese manager claimed that even though two red and seven yellow cards does not look great on paper, he feels that they were not rewarded as a result of his side being malicious in tackles but that it was simply circumstance of the clash.
Villas-Boas told the club’s official website: “It is just the nature of the game. There are better years and years where you don't get yellow cards.
"We have to just deal with it - as you start accumulating them suspensions come early so we have to manage it as technical staff to get the most availability as possible.
"It doesn't mean a pattern of bad behaviour or aggressiveness.
"I think there is a [Jon Obi] Mikel yellow card with us with nine men when he is confronted one against one before the player goes into the box and he chooses to foul the player instead of giving the player an opportunity to score. Things are related to other things and other stories.
"Didier's challenge is a sending off for sure and you cannot appeal but the other one is not in my opinion."
The Chelsea boss is hoping his side can bounce back to form after the loss, looking for his players to put in a performance as they face both Everton and Arsenal in the space of three days.“We should have played better with 11 men and committed less mistakes, and if we do that we avoid a couple of situations," he explained.
“And if with nine men we are able to do that to Queens Park Rangers, with 11 men we should be able to do it.
“You expect better things from us with 11 men but on the other hand it happened. You have to analyse the game thoroughly. You can take the view that with 11 men we were not good enough with the same fluency at the start. Then we were down to 10 men pretty early due to a bad decision.
“We have suffered before in early parts of the game, for example against West Brom, and we were able to react. We have been with 10 men before and we won 4-1 against Swansea.”
Chelsea have been charged by the FA for their behaviour at Loftus Road and have been given until October 28 to respond.
