London side, Arsenal extended their unbeaten run to 20 games, after they were held 2-2 by Manchester United at Old Trafford on Wednesday.
Arsenal led twice, either half through goals by Shkodran Mustafi and Alexandre Lacazette (Marco Rojo).
But United responded almost instantly. Anthony Martial and Jesse Lingard twice quickly levelled to earn a 2-2 draw with Arsenal and offer some rest bite to beleaguered manager Jose Mourinho
Mourinho’s men remain eight points off the top four in eighth place after a fourth straight league game without a win.
Mourinho had opted to leave out-of-form big name stars Paul Pogba and Romelu Lukaku on his bench and when United conceded first, for the 11th time in 21 games this season.
