London:Leeds United took over at the top of the English Premiership on Sunday after a 3-0 victory over Derby County. After a poor finishing from the Leeds attack, Harry Kewell sealed the victory with two goals late in the second half. Leeds now have a two-point cushion over their nearest rivals Bolton Wanderers. Derby seemed to take an early lead when Rio Ferdinand slid in to cut off a cross from Malcolm Christie and bundled it into his own net, but the goal was disallowed for offside. Slack marking allowing Eirik Bakke to get a free header to Ian Harte's corner and Leeds get their first goal. Leeds went in with a 1-0 lead at the break. The Leeds defence looked solid throughout, but they knew their slender lead wasn't enough. As the home side's frustration grew, Harry Kewell finally found his finishing touch and planted the ball in the back of the net with a fine left foot shot to give Leeds a 2-0 cushion. Three minutes later the Leeds fans were singing again as Kewell put the game beyond Derby's reach with his second goal of the match. The home side could have finished with another three or four goals in the last ten minutes had it not been for Andy Oaks excellent goalkeeping. The Derby keeper twice denied Robbie Keane and then kept out two Lee Bowyer efforts but it wasn't enough to avoid defeat.
