Former Wales international John Hartson believes that Swansea City have enough quality to snatch three points from Manchester United.
The two sides go head to head on Sunday and the Red Devils need to achieve victory in order to stay in contention for the Premier League title.
"Swansea are capable of going to Man United and winning. That's how much I rate this young side," Hartson told BBC Sport.
Sir Alex Ferguson's team are currently second in the table due to Manchester City's superior goal difference.
