Kagawa steals show as United march on

(CNN) -- Shinji Kagawa scored a hat-trick as champions-elect Manchester United crushed Norwich City 4-0 at Old Trafford in the English Premier League on Saturday.

It was a 39-year-old Welsh winger that was expected to hog the headlines this weekend but Ryan Giggs, who was due to play his 1,000th game, was left out of Alex Ferguson's squad. Instead, it was the 23-year-old midfielder from Kobe whose face will be plastered over the back pages of Sunday's newspapers.

The Japan international opened the scoring with a fine volley in first-half stoppage time before grabbing a second, then a third in the 76th and 87th minutes as United finished another game in rousing fashion.

Wayne Rooney added a fourth in injury time to complete the rout to send the Red Devils 15 points clear at the top of the table and coasting towards a 20th League title.
