Chelsea boss Andre Villas-Boas was very critical of the refereeing as his side fell 1-0 to West London rivals QPR at Loftus Road.
The Blues conceded a penalty which was scored by Heidur Helguson in the 10th minute before losing Jose Bosingwa and Didier Drogba to red cards in the first half.
Despite being so disadvantaged, Chelsea came close to snatching a point with a few chances late in the match and that aspect pleased Villas-Boas although he was extremely unhappy with the performance of referee Chris Foy and his match officials once again.
"I have to praise the players because they were amazing," he told Sky Sports 1.
"For 45 minutes we played with nine men and that takes courage, it shows the strength and commitment of squad.
"It's the third time in row where a referee has directly influenced the result for us and we're not happy with this. In three games there have been blatant refereeing mistakes.
"I'm very disappointed with Chris' performance. With nine players we kept our emotions very well. Chris and his team managed to play an emotional game and they conceded to the crowd and committed tremendous mistakes."
