Ferguson said: ''The penalty kick was so soft. Deary me. But we played very well. It was a great performance by us. We didn't deserve that. That's three years in a row [at Stamford Bridge] referees' decisions have changed the game.''
On the Luiz decision, he added: ''It was incredible. Even before that he'd done Chicharito off the ball. He'd done him late. Nothing done, the referee's in front of it.
''He does Rooney clear as day, (the referee is) six yards from it, he doesn't do anything. That changed the game. These are decisions that change the game. And he's going to be refereeing every week.
