Arsenal maintained their Premiership supremacy with a 2-0 home win over Blackburn Rovers on Monday. The Gunners have competently capitalized on Manchester United's shock defeat to Manchester City on Sunday, opening a five-point lead over the champions. Philippe Senderos gave the home side an early lead with a fourth-minute header, before Emmanuel Adebayor rounded off the game with an injury time strike. Arsenal reached 63 points at the summit, while Rovers remain ninth on 39 points. Arsene Wenger's team will clash with European champions AC Milan in the Champions League knock-out stage next week.
