Watch: Slick set piece helps Bournemouth upset 10-man Arsenal

Bournemouth took a page out of Arsenal's set-piece playbook on Saturday, executing a clever corner-kick routine of their own to become the first team to beat the Premier League title hopefuls this season.

Ryan Christie lashed home Bournemouth's first goal in the 70th minute after Justin Kluivert tipped Lewis Cook's corner into his teammate's path.

Kluivert secured the 2-0 win for the Cherries from the penalty spot nine minutes later. Arsenal 'keeper David Raya conceded the spot-kick after chopping down Evanilson, who was only in scoring position thanks to Jakub Kiwior's woeful back pass.

Arsenal played more than an hour with 10 men after defender William Saliba was sent off by the VAR for a last-man challenge.

The red card was their third in eight league matches.

The Gunners could find themselves as far as four points out of first place if Liverpool beat Chelsea on Sunday.
