It was the sixth, and most devastating home defeat of what has been a long and painful debut season for United manager David Moyes.
The last time United lost six league matches at home was in 1978 and that is a statistic which Rooney feels is unacceptable.
"It's not good enough," Rooney said in a frank interview with MUTV.
"We can't lose six homes games in a season and we have to put that right, and make this a place which teams fear again."
