Southampton vs Arsenal LIVE: Premier League result, final score and reaction

That's all from St Mary's today, so thank you for joining us and goodbye!

After losing for the first time in seven encounters with Southampton, today's defeat means Arsenal have taken just four points from losing positions this season - perhaps summing up their most major flaw. They travel to Stamford Bridge in midweek for a crucial London derby with Chelsea - and face Manchester United next weekend - while Saints visit Burnley on Thursday with a top-half finish still in sight.

Another setback for Arsenal's top-four ambitions sees Arteta's men slump to a third straight defeat, after their efforts to break down an obdurate Southampton side come to nothing in the end. The hosts were willing to cling on grimly during the second half, having taken the lead towards the end of the first, and Forster's heroics kept their visitors at bay. Ultimately, having three-quarters of the possession proved fruitless for the Gunners, as they spurn the opportunity to capitalise on Tottenham's slip-up earlier today.

FULL-TIME: SOUTHAMPTON 1-0 ARSENAL

A lung-bursting run by Long charges down Ramsdale's attempted clearance, and the Saints striker celebrates with the home fans as if he'd just scored the winner. That's it, they've held on!

A wild, desperate swipe at goal from 20 yards out by Martinelli sends the ball careering over the to pof the Southampton crossbar, and the home side have surely hung on for all three points now.

With less than three minutes of stoppage time remaining, Ward-Prowse whips a free-kick at goal from the left side of the area, but his shot is saved by Ramsdale.

Long buys some valuable time after going down under a challenge from Xhaka in midfield, and Saints look to be preparing another substitution - no doubt helping to run down the clock.

Every red-and-white Southampton shirt remains tightly assembled inside their defensive third, but Arsenal just cannot break through. Even when they manage to pick out the goalframe - they have had 17 attempts but only three on target - Forster appears unbeatable.

FORSTER AGAIN! This time, Southampton's one-man barrier denies Xhaka, whose side-footed effort from 20 yards was perhaps set to miss the far post, but Forster wasn't to know. Another fine stop!
