Arsenal mounted a dramatic comeback from three goals down to rescue a point from a spirited Bournemouth side.
The hosts started with vigor, scoring twice in the opening minutes, taking an early lead as Charlie Daniels cut inside Hector Bellerin and stroked a shot past on-rushing keeper Petr Cech.
Callum Wilson then converted a penalty to extend Bournemouth’s lead and Ryan Fraser sent a shot through Cech’s legs for the Cherries’ third just before the hour.
The Gunners had looked set to leave Dean Court empty handed and appear headed for their third consecutive defeat away from the Emirates stadium. Bue when the 70th minute came Alexis Sanchez headed in at the far post from an Olivier Giroud flick.
The game appeared to have a dramatic shift entirely to Arsenal’s favour with Sanchez’s goal, and by riding the momentum, Arsenal bagged their second just five minutes later when substitute Lucas Perez volleyed into the far corner.
With eight minutes left, Simon Francis went into a full-blooded challenge with Aaron Ramsey that referee Michael Oliver deemed harsh enough for a straight red. Down to 10 men, Bournemouth, who was retreating deeper and deeper, desperately tried to hang on.
As the hosts slowly buckled under Arsenal’s pressure, the game went into the 92nd minute when Granit Xhaka delivered a cross that Giroud, towering above Steve Cook, headed beyond Artur Boruc.
Their defending flaws notwithstanding, Arsenal displayed strength in character as they managed to muster resilience that kept them fighting – with extra credit given that this was their second fixture in the space of two days.
Thanks to their spirited comeback, the Gunners would also earn a precious point – although it appear an almost pointless gain as Chelsea equaled their record of 13 Preimer League wins and continue to stretch their lead at the top the Premier League table.
