Chelsea manager Andre Villas-Boas has denied an FA charge of improper conduct following his comments about referee Chris Foy after the defeat to QPR last month.
The club confirmed in a statement that Villas-Boas would be contesting the charge after his remarks about Foy's performance in Chelsea's 1-0 defeat at Loftus Road - a match they finished with just nine men.
A statement on the club's official website read: "With regards to the FA charge against Andre Villas-Boas for remarks he made after the QPR game, the manager is denying the charge against him and has submitted his response to the Football Association."
The Portuguese also admitted that he had confronted the referee post-match and said the two teams had been treated differently: "I spoke to him at the end and I was very aggressive to him. I don't care if he's okay or not.
"I'm not happy with the difference of treatment. I don't think the same treatment was applied. Apart from the fourth official, the other three were led by the emotions of the crowd and couldn't deal with a game like this.
"Three of the games played by Chelsea were influenced by the referee, and this is not Premier League level. You have to trust human error, but it's a big pattern for us. Things are not going our way.
"Conspiracy theories can lead to bans and lead to you calling us cry babies, and we're not, but it keeps happening."
Chelsea have already accepted a charge of failing to control their players during the game, and were subsequently fined £20,000, but Villas-Boas is now facing the prospect of further punishment.
