Andre Villas-Boas tasted defeat for the first time as Chelsea manager on Sunday when the Blues lost 3-1 at Old Trafford, with Manchester United racing into a 3-0 lead before Fernando Torres pulled a goal back in the second half.
Replays suggested that the Red Devils’ first two goals should both have been disallowed, with Chris Smalling in an offside position when scoring the first before Nani wandered back from being offside to launch a long-range effort that doubled the home team’s advantage.
Now that Villas-Boas has had time to consider the match, he feels strongly enough to lodge a complaint to referees’ chief Mike Riley about the sense of injustice felt about the refereeing decisions that were made on the day.
Villas-Boas said: “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. 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.”
One of the game’s talking points was the Ashley Cole foul on Javier Hernandez towards the end of the match that saw the Chelsea player booked, although Villas-Boas defended his player by claiming he was emotionally drained by that point.
