Mikel Arteta has revealed Bukayo Saka is a doubt for this weekend's game against Bournemouth after being forced off in the closing stages of the north London derby.
Saka was replaced deep into stoppage time during the 2-2 draw with Tottenham, after forcing Cristian Romero into an own goal and scoring from the penalty spot, and the winger is almost certain not to be risked in Wednesday's Carabao Cup third-round tie at Brentford.
