William Saliba's first-half red card set Arsenal on their way to a 2-0 defeat against Bournemouth at the Vitality Stadium as Mikel Arteta's side missed the chance to go top of the Premier League.The defender was dismissed for hauling down striker Evanilson near the halfway line, denying him a clear run on goal as for the third time this season the visitors finished a league game with 10 men.Andoni Iraola's side saw a chance to inflict Arsenal's first loss of the season and took it most clinically, taking the lead 20 minutes from time when substitute Ryan Christie hit an unstoppable effort into the top corner just as Arsenal appeared to have come through unscathed from the worst of Bournemouth's pressure.Arsenal pushed on and inevitably left gaps.
Evanilson took advantage when he got in behind and was felled by goalkeeper David Raya, handing Justin Kluivert the job of capping a fine victory from the penalty spot.An uneventful opening 20 minutes saw the Gunners limited creatively by Bournemouth's disciplined high press, the closest either side came to a goal when Raya gifted the ball with a dreadful pass only for Antoine Semenyo to thrash at the chance.The shape of the game shifted with the sending off in the 30th minute.
Evanilson still had the whole of the Arsenal half to traverse in pursuit of a looped ball over the top but crucially had manoeuvred goal side of Saliba and threatened to race clear.Saliba was the last man - there was little chance of Ben White making up the distance to cover from right-back - and clearly dragged Evanilson to the ground, though it took a pitch-side review to convert Robert Jones' initial yellow card to a red.Arsenal had gone down to 10 against Brighton and Manchester City this season and
