Hat-trick hero Berbatov keeps United on top

Dimitar Berbatov grabbed his third hat trick of the season to guide unbeaten Premier League leader Manchester United to a 5-0 thrashing of Birmingham

Wingers Ryan Giggs and Nani were the other scorers for United, which swept to an emphatic victory at Old Trafford to move to 22 games without a defeat.
Berbatov, who is the league's leading scorer with 17 goals, became the first player to score three Premier League hat tricks in a season since Ruud van Nistelrooy achieved the feat for United in the 2002-03 campaign.
Van Persie put Arsenal in front in the 21st in a one-sided match against 10-man Wigan at Emirates Stadium and the Netherlands international added further goals in the 58th and 85th.
He blotted his copybook by missing a second-half penalty, which would have taken him to seven goals in his last three games.
Arsenal stayed two points behind United in the standings.
Manchester City could join United on 48 points by beating Aston Villa away later on Saturday. Fourth-place Chelsea visits Bolton on Monday.
Kenny Dalglish claimed his first victory since returning as manager of Liverpool as the Reds defeated Wolverhampton 3-0 away thanks to Fernando Torres' double and a sublime volley by Raul Meireles.
Wolves are now level on 21 points with bottom side West Ham, which conceded a late goal at Everton to draw 2-2.
England winger Aaron Lennon grabbed a last-minute equalizer for fifth-place Tottenham in a 1-1 draw at Newcastle, Sunderland beat Blackpool 2-1 to move a point behind Spurs and United States midfielder Clint Dempsey's brace helped Fulham to a 2-0 win over Stoke.
United's stunning record at Old Trafford now stands at 11 wins and a draw from its 12 home matches, with beleaguered Birmingham forced on the back foot for the entire match.
Berbatov gave United the lead after just two minutes with a close-range header and added the second in the 31st. He then linked with Wayne Rooney to set up Giggs for the third just before the break, before completing his hat trick by sliding home Giggs' cross in the 53rd.
Nani rounded off the scoring with a long-range strike in the 76th as Birmingham failed to end a winless run against United that stretches back to 1978.
Arsenal's win over Wigan was just as one-sided, with the Latics indebted to goalkeeper Ali Al Habsi for keeping the scoreline down.
Van Persie's return to fitness has given the Gunners more of a cutting edge up front and the Dutch striker was in ruthless form as he lashed home the opener from the angle after being put through by Alex Song.
Cesc Fabregas provided the through-ball for Van Persie's second and the Spain midfielder was brought down by Gary Caldwell in the 69th minute, leading to the Wigan defender being sent off and presenting Van Persie with a perfect chance to claim his hat trick.
Van Persie smashed the spot kick over the bar but he wasn't to be denied as he ran onto Theo Walcott's pass to power home another well-taken finish.
Torres took his tally for the season to nine goals by scoring Liverpool's first and third at Molineux. The Spain striker's double sandwiched a stunning volley by man-of-the-match Meireles in the 50th, with Liverpool's first win since Jan. 1 lifting the team into midtable.
West Ham twice took the lead against Everton- through Jonathan Spector and Frederic Piquionne- but were pegged back both times, with Diniyar Bilyaletdinov equalizing first and Marouane Fellaini netting the second leveler a minute into injury time.
Lennon's late strike canceled out Newcastle's opener scored by Fabricio Coloccini at St. James' Park, while Kieran Richardson's first-half brace proved enough for sixth-place Sunderland against Blackpool. Midfielder Charlie Adam got the hosts' consolation at Bloomfield Road.
