Mikel Arteta was left to rue his side's defensive mistakes after seeing his side beaten 2-0 at Bournemouth to slip to their first Premier League defeat of the new season.
William Saliba left Arsenal with a mountain to climb after being sent off in the first half. The Frenchman was initially shown a yellow card for a tug on Evanilson but it was upgraded to a red to leave the Gunners down to 10 men.
A well-worked Bournemouth goal then saw the Cherries go ahead when Ryan Christie smashed home from a corner to make it 1-0. Nine minutes later, David Raya conceded a penalty for a foul on Evanilson, allowing Justin Kluivert to finish Arsenal off and secure all three points.
