Avram Grant took a leaf out of Jose Mourinho's book by pointing the finger at the referee after Chelsea slumped to a 2-0 defeat to Manchester United in the Israeli's first game in charge.
Chelsea have already launched an appeal against the dismissal of Mikel Jon Obi by referee Mike Dean for a two-footed tackle on Patrice Evra in the Barclays Premier League clash at Old Trafford.
But Grant also claimed Carlos Tevez's opener came after first-half injury time, that Louis Saha's penalty should not have been awarded and Wayne Rooney should have been sent off.
"Sir Alex Ferguson can be more than happy with the referee. The referee tried his best but he made three mistakes; the red card, their first goal and the penalty. I am also surprised Rooney was not shown a second yellow card," he said.
"Maybe I am being naive but I wonder what Sir Alex's reaction would have been if he was in my position."
Ferguson, though, insisted Joe Cole should have been sent off for a bad foul on Cristiano Ronaldo.
"Joe Cole should have been sent off," Ferguson said. "Tackles like that are a danger to players. He went right down the back of his leg and could have done some real damage.
"It is the type of thing Cristiano is facing all the time now but Cole got off with it because the referee was balancing things out after the first sending-off.
"The referees are not punishing tackles like that in the right way. I was very angry about it."
Meanwhile, Chelsea insist Avram Grant's lack of a UEFA Pro Licence will not stand in the way of him managing the side on a long-term basis.
The club have already set in process an application for the 52-year-old Israeli to either be given the licence on the basis of his experience and other qualifications or for him to start to take the courses.
