Arsenal scored three times in 20 minutes to wipe out a 3-0 deficit and claim a point in a thrilling match at Bournemouth.
Olivier Giroud, whose 'scorpion' goal had made headlines in the win over Crystal Palace, rose at the far post to glance home a 91st-minute leveller against a home side reduced to 10 men.
Bournemouth had made a high-tempo start but it was Arsenal who threatened first when Alexis Sanchez played in Hector Bellerin to provide a dangerous cross that was well dealt with by Nathan Ake.
Soon afterwards, Aaron Ramsey was almost threaded through by another Sanchez touch -- but the home side hit back quickly and tested visiting goalkeeper Petr Cech with a Junior Stanislas effort from range.
