Stamford Bridge boss unhappy with refereeing standards.
Chelsea manager Andre Villas-Boas was so angry about the levels of performance from the match officials in the defeat at Manchester United he made a complaint.
The Blues boss is still annoyed by the manner of what was his first loss in charge of the Blues and his first defeat in a league game for 17 months.
The 33-year-old was so incensed by the referee Phil Dowd and his assistants he reported them to the officials chief Mike Riley.
Chelsea fell 2-0 behind at Old Trafford on Sunday to goals which replays showed should not have stood as both scorers had been offside.
“Very, very unhappy with a poor performance from the referees, which in the end had a decisive role in the result, and I don’t take it very, very lightly,” AVB said.
“You expect the linesman to do his job. I already went further ahead with the situation by speaking to the correct people.
“We all feel very, very down when the referee had such an impact on the result.”
Villas-Boas also announced Josh McEachran, Romelu Lukaku, Oriol Romeu and Ryan Bertrand would all start tomorrow in the Carling Cup, with Didier Drogba leading the line.
