Arsenal extended their lead at the Premier League summit to five points after beating Blackburn 2-0 in a tough encounter at The Emirates.
Swiss defender Philippe Senderos struck early on at the Emirates Stadium with a free header and the Gunners could have added more, only for Brad Friedel to put in an outsatnding display to keep the visitors in the game.
Mark Hughes' men even threatened themselves at times but Arsenal held on, with in-form striker Emmanuel Adebayor adding a second in stoppage-time after good work from Alexander Hleb to take advantage of their title rivals dropping points at the weekend.
Arsene Wenger's men were the beneficiaries of results at Old Trafford and Stamford Bridge - and now have 12 games remaining to make the most of their lead in search of their first title since the Invincibles of 2004.
