O'Neill toasts Van Persie's quality

Martin O'Neill believes Robin van Persie could make the difference for Manchester United this season.

Van Persie scored his 15th goal of the campaign as United recorded a 3-1 win over Sunderland at Old Trafford to remain six points clear of Manchester City at the top of the Barclays Premier League.

"Robin van Persie was a great purchase," said O'Neill. "It means Manchester United are capable of scoring goals because Wayne Rooney is a top quality player as well.
