Manchester City manager Roberto Mancini claims his team are being victimised by officials after Samir Nasri was sent off for a head-butt in the champions' 4-3 win at Norwich.
The Italian was unhappy with the decision of referee Mike Jones to show Nasri a red card following a clash of heads with Norwich defender Sebastien Bassong, who was only booked for his part in the first half incident at Carrow Road on Saturday.
Mancini has already been asked by the Football Association to explain comments after the 1-0 defeat at Sunderland on Wednesday that referee Kevin Friend "ate too much for Christmas".
City will appeal against Nasri's red card, which will otherwise result in a three-match ban, but whether the governing body will be impressed by Mancini's conspiracy theory claims remains to be seen.
"Both players came forward with their heads, so if you are going to send off one, then you have to send off both, not only Samir," he said.
"Samir said he touched his head, okay, but the other player has done the same. "The linesman has a big responsibility also, because it was not a good decision, it is incredible.
"You want to send off both players? Then, OK, the referee was there, he saw everything. The linesman was behind the players, he could not see. We will appeal, sure." Mancini admitted that Nasri had only himself to blame for reacting so angrily to Bassong's challenge a minute before the break, but he suggested City are treated with less leniency than other teams.
