The Blues lost 2-1 in the London derby clash with Arsenal on Sunday.
“Chelsea and the referee (were responsible for the defeat) because Arsenal scored the first goal one metre in front of our players and in the first half the same linesman gave (Salomon) Kalou offside when it was not,” he told Sky Sports.
“It is important to speak to the people about this because if we play and the referee gives two things against my team sometimes it is difficult to win.
“OK I make mistakes but we needed a man to come to Stamford Bridge as a referee for both sides, not for one side.”
