The Cherries raced into a 3-0 lead but goals from Alexis Sanchez, Lucas Perez and Olivier Giroud completed a remarkable comeback for the Gunners on Tuesday. Arsenal came back from three goals down to draw 3-3 with Bournemouth and keep their Premier League title alive on Tuesday.
Bournemouth raced into a 2-0 first-half lead thanks to a goal from Charlie Daniels and a penalty from Callum Wilson after Ryan Fraser was brought down by Granit Xhaka.
Fraser soon made it 3-0 after the break before Arsenal hit back through strikes from Alexis Sanchez and Lucas Perez.
And after Cherries were reduced to 10 men after Simon Francis was sent off for a bad tackle on Aaron Ramsey, Olivier Giroud completed the remarkable comeback by finding the back of the net late on.
