  1. Southampton 1-0 Arsenal

    Over an hour gone. As it stands, Southampton are heading into the next round. The defending champions need a goal or they're going out.

    Cedric Soares has just been penalised for a foul throw.

  2. 'You can sense something'

    Southampton 1-0 Arsenal

    Alan Hutton
    Former Aston Villa defender on BBC Radio 5 Live

    Much better play now from Arsenal, you can just sense something.

    These substitutions have just given everybody a lift.

  3. CLOSE!

    Southampton 1-0 Arsenal

    Decent chance for Arsenal!

    It comes over to Rob Holding in the box after Eddie Nketiah's shot is blocked. He should hit the target but he fires it over the bar.

  4. SUBSTITUTION

    Southampton 1-0 Arsenal

    Thomas Partey is coming on for Arsenal. He replaces Mohamed Elneny.

    Gabriel Martinelli is also off. Bukayo Saka is on.

  5. Southampton 1-0 Arsenal

    Looks like Thomas Partey is getting ready to come on...

  7. Southampton 1-0 Arsenal

    Eddie Nketiah is brought down by Jan Bednarek on the right but nothing comes of it from the free-kick.

  8. Southampton 1-0 Arsenal

    Ryan Bertrand is played through on the left. He puts a good ball in towards the near post, it's deflected away to James Ward-Prowse but he skies it over the bar.

  9. HITS THE WOODWORK

    Southampton 1-0 Arsenal

    Danny Ings thinks he's onside as he races onto a long ball. He strikes it powerfully off the right post and it bounces back off Bernd Leno and rolls just wide.

    The flag eventually goes up but that was tight!

  10. Southampton 1-0 Arsenal

    Alan Hutton
    Former Aston Villa defender on BBC Radio 5 Live

    That was a great breakway from Arsenal, Nicolas Pepe using his pace but great play from Ibrahima Diallo getting across.

  11. Southampton 1-0 Arsenal

    Bernd Leno gathers in the free-kick and Arsenal try to set Nicolas Pepe off down the right. Ibrahima Diallo matches him for pace, gets a tackle in and Theo Walcott is then brought down by Willian.

    Sarah Morgan: I'm an Arsenal fan but have a lot of liking and respect for Southampton. They play great football and I love the loyalty of their players and board. They rightly refused to scapegoat Hasenhuttl for a bad situation and I'm so glad they kept him on to turn it around!

  13. Southampton 1-0 Arsenal

    Gabriel Martinelli catches Kyle Walker-Peters late near the touchline. Early free-kick for James Ward-Prowse.

  14. KICK-OFF

    Southampton 1-0 Arsenal

    Back under way. Southampton just need to keep doing what they're doing. Arsenal need to improve massively.

    EddieRockSteady: Arsenal really inviting trouble upon themselves spending so much time with the ball in their own half. Almost like they came here not to lose instead of going for a win. Not sure if they know a draw isn't an option today, mind...

    ArtetaIn: You can’t praise Southampton for this, they’re nothing special. This first half has all been on Arteta’s woeful selection, and weird obsession with Elneny.

  16. HT: Southampton 1-0 Arsenal

    Any changes needed at half time, Arsenal fans?

    Bukayo Saka, Alexandre Lacazette, Thomas Partey and Ainsley Maitland-Niles are among the substitutes.

  17. Get Involved

    #bbcfootball or text 81111 (UK only)

    Arteta right to rotate, Arsenal going into a tough run in the league. Lack of squad quality being exposed here though.

    Mike in Hants

    Saints have bossed it, so expecting changes by Arteta. Once again, Willian has offered absolutely nothing, complete waste of a jersey.

    Mark in Swindon

  18. The difference so far

    HT: Southampton 1-0 Arsenal

  19. 'Southampton have been excellent'

    HT: Southampton 1-0 Arsenal

    Alan Hutton
    Former Aston Villa defender on BBC Radio 5 Live

    Southampton have been excellent, well worth their lead, aggressive in the press and trying to make things happen.

    Ralph Hasenhuttl will be over the moon with his team, it's going to be Mikel Arteta who will be more disappointed.

  20. End of a clean run

    HT: Southampton 1-0 Arsenal

    Gabriel’s own goal was the first goal Arsenal have conceded since Tammy Abraham’s strike for Chelsea on Boxing Day, ending a run of 508 minutes without conceding in all competitions.
