Arsenal failed to find a way past Southampton, denied by an inspired performance from goalkeeper Fraser Forster.
The Gunners could only manage a 0-0 draw, the third league game in a row they have failed to find the net.
They have slipped from top of the league to fourth place, and need to turn their form around quickly to stop them losing further ground.
The loss of midfielder Santi Cazorla to injury has evidently been problematic for the Gunners, and last night they lined up with veteran Mathieu Flamini in midfield, with Francis Coquelin not judged ready.
Perhaps more concerning was the performance of Aaron Ramsey, who has gone from being a game changer two seasons ago, to looking consistently ineffective.
The goals are gone from his game, managing just one shot on target on the night, and that one he fired straight at Forster.
Defensively he managed only one tackle, and one interception, and despite touching the ball more than any Arsenal player at 96 times, did not have a big effect on proceedings.
Returning to his favoured position was a big chance for the Welshman to kick on and re-establish himself, but he needs to do better than this if Arsenal are to be successful.
Here is a look at how Arsenal fans reacted to his performance...
Ramsey is not improving at all. He has his moments of brilliance, but those moments r beginning to happen too few and far between #afc— Rockstar★Gunner (@Mr_Rock_Star) February 2, 2016
Our midfield double of Ramsey and Flamini is atrocious. Barcelona will humiliate us. Let's give Coquelin and Elneny a run of games. #afc— Bryan B Ruhamba (@Blitz_RBB) February 2, 2016
Awful performance. Ramsey and Giroud the biggest culprits. No where near title challengers. #afc— Matt Kett (@matthewKett) February 2, 2016
The Ramsey love in needs to stop he's no good, living off few years ago & believing the hype he's stopped trying. #AFC— Robdagooner (@RobWoodfin1) February 2, 2016
We so much miss Carzola. Ramsey has been invisible for 4 games in a row now #afc— Smalls_afc (@RavelloConsult) February 2, 2016
Ramsey has been awful in his last two games, what a way of saying thanks to getting his best position back #afc— Romano'sArmoury (@romanosports1) February 2, 2016
Everyone who favored Ramsey over Cazorla in the CM role, hold your heads down in shame. Move Ramsey to RW or better off, to the bench #AFC— Emeke John (@sisquo_delgado) February 2, 2016
