Chelsea beat Manchester United 2-1 in a dramatic match at Stamford Bridge on Saturday to pull level at the top of the Premier League and keep alive their hopes of snatching the title from United’s grasp.Michael Ballack was Chelsea’s hero, deciding the game with an 86th-minute penalty after heading the home side ahead at the end of the first half. The Chelsea players celebrated that goal by unfolding a number eight shirt with “Pat Lampard RIP” on the back following the death of midfielder Frank Lampard’s mother on Thursday. Wayne Rooney equalised for the visitors when his 56th-minute shot went in off the post after a careless backpass from Ricardo Carvalho. Both teams have 81 points, although United remain top because of a better goal difference. United will still win the title if they match the same number of points that Chelsea collect from their last two games at Newcastle United and at home against Bolton Wanderers. United’s last two league games are at home to West Ham United and away at Wigan Athletic. In other matches, Liverpool drew with Birmingham City 2-2, while Manchester City lost to Fulham 2-3. Tottenham Hotspur were held to a 1-1 draw by Bolton Wanderers and Sunderland defeated Middlesbrough 3-2. There was another draw at Upton Park, where Newcastle held West Ham 2-2.
