Manchester United boss Sir Alex Ferguson has questioned the number of penalties rivals Manchester City are given at home, reports BBC Sport. Since the start of the 2010-11 season City have been awarded 20 Premier League spot-kicks at home to Manchester United's 13.
However, last season United were given nine penalties at Old Trafford - one more than their neighbours.
"If we got that number of penalty kicks there'd be an inquiry in the House of Commons," the United boss said.
"There'd be a protest."
Opta stats show that City have been awarded four penalties at home so far this Premier League season, scoring three. United have missed both of the two they have won at Old Trafford.
