Arsenal manager, Arsene Wenger will have to wait for another day to defeat Jose Mourinho in the league as Olivier Giroud’s 89th-minute equaliser earned the Gunners a point and denied the Red Devils a victory they deserved at Old Trafford.
Juan Mata looked to have put United on course for three points with a sweeping left-foot finish from Ander Herrera’s cut-back after 68 minutes.
Arsenal had not had an effort on goal but secured the draw that leaves them six points ahead of United when substitute Giroud rose at the far post to head home Alex Oxlade-Chamberlain’s cross.
United had controlled a game that was ordinary for long periods, with Arsenal keeper Petr Cech making important interventions and Mourinho left furious that they were denied a first-half penalty by referee Andre Marriner when Nacho Monreal hauled down Antonio Valencia.
