Manchester: Manchester United won their 20th league title on Monday when a Robin van Persie hat-trick led them to 3-0 victory over Aston Villa and gave them an unassailable 16-point lead over last season's Premier League champions Manchester City.
Van Persie's goals after two, 13 and 33 minutes - the second among the best scored at Old Trafford - propelled Alex Ferguson's side to victory in front of a jubilant home crowd.
