Football: Kagawa hat-trick gives United 4-0 win over Norwich

MANCHESTER (AP) - Shinji Kagawa scored a hat-trick on Saturday as Manchester United kept their firm grip on the English Premier League title with a 4-0 win over Norwich at Old Trafford.

The Japan international put United ahead right before half-time and then added two more in the second half to make sure United extended their lead over Manchester City to 15 points ahead of their cross-town rivals' game against Aston Villa on Monday.

Wayne Rooney capped off a dominant display with a looping long-range strike into the top of the net in the 90th minute.
