Leandro Trossard has bagged his eleventh goal of the Premier League season with a clinical finish from the right-hand side of the box.
After a dominant display in the first half which saw the Gunners enter the break one goal up, courtesy of a Bukayo Saka penalty, the complexion of the contest completely changed after the break.
As nerves around the Emirates began to grow, so did Bournemouth’s confidence as they began to sustain possession in Arsenal’s final third.
But the pressure valve was released in the 70th minute when Trossrad curled home a second after some smart play from Declan Rice inside the area.
