The Frenchman was again on hand off the bench as Arsene Wenger's men snatched a late draw, leveling the game after a Juan Mata opener
Olivier Giroud's 89th minute header snatched a point for Arsene Wenger's Arsenal as they drew 1-1 with Manchester United on Saturday.
The Red Devils looked certain for all three points as the Gunners failed to register a shot on target before Giroud's effort.
Juan Mata had put the hosts ahead, the Spaniard linking cleverley with compatriot Ander Herrera before slipping the ball past Petr Cech in the Arsenal goal.
Mourinho looked set to continue his impressive run over Wenger before Giroud nodded in an Alex Oxlade-Chamberlain cross with their only shot on target of the game.
