  1. 'Too easy for Chelsea'

    Chelsea 1-0 Arsenal

    It is too easy for Chelsea going forward. When Arsenal get the ball they are just giving it away.

  2. Chelsea 1-0 Arsenal

    Another ball over the top, this time from Willian, and if Chelsea forward Pedro was a size nine instead of a size eight, he would have got on the end off it.

    Passing out from the back may work in the future, but against a team with the quality of Chelsea is begging to be punished.

  4. Chelsea 1-0 Arsenal

    Arsenal are a shambles at the back.

    Chelsea are getting in behind with simple balls over the top.

    This time N'Golo Kante holds it up for Ross Barkley, but the Englishman's left-footed shot is over the crossbar.

  6. 'Poor defending from Arsenal'

    Chelsea 1-0 Arsenal

    John Southall
    BBC Radio 5 live football reporter

    There is no one within 10-15 yards when Pedro hits it. Poor defending, but It was with the run of play.

    Mark: The new Arsenal philosophy of playing out from the back has already shortened my life expectancy by 10 years.

    KoloKK: Arsenal have joined the play-out-from-the-back club. But have they mastered it yet, is what is left to be seen.

    Dan: Did Unai Emery sign some sort of clause in his contract that Granit Xhaka and Petr Cech must play every game? Absurd how they get picked week in week out.

  8. goal

    GOAL - Chelsea 1-0 Arsenal

    Pedro

    Chelsea

    Arsenal ripped apart at the back.

    Chief architect Jorginho is the creator, sweeping a ball to the left for Marcos Alonso.

    The Spaniard is in behind the Gunners defence, looks up and plays the ball across for fellow countryman Pedro, who coolly finishes into the bottom corner.

  9. CLOSE!

    Chelsea 0-0 Arsenal

    Oof, inches away from the first goal of the game.

    Arsenal patiently work an opening and full-back Nacho Monreal clips in a cross which the galloping Mesut Ozil flicks first time but wide of the far post.

  10. Chelsea 0-0 Arsenal

    Arsenal content to sit back, let Chelsea have the ball.

  11. Get Involved

    #bbcfootball or text 81111

    The key from Arsenal's perspective today would be to manage N'Golo Kante-Jorginho combination. I'm really doubtful Granit Xhaka and Matteo Guendouzi will be up for the challenge. That's where the game probably will be lost for us.

  12. Chelsea 0-0 Arsenal

    Chelsea looking the more assured with the ball at their feet.

    Summer acquisition Jorginho looks up and plays a lovely ball over the top of the Arsenal defence, but Ross Barkley is inches away from controlling it.

  13. Chelsea 0-0 Arsenal

    Phil McNulty
    BBC Sport chief football writer

    Unai Emery is already pacing up and down his technical area almost wanting to direct every movement from his Arsenal players. Plenty of tic-tac from Maurizio Sarri too.

    Will give Unai Emery time to make his mark, but if he keeps starting Granit Xhaka I'm going to lose patience sooner rather than later.

  15. CLOSE!

    Chelsea 0-0 Arsenal

    Chelsea centre-back David Luiz steps up from the backline and dips a 35 yard shot narrowly over.

    Arsenal goalkeeper Petr Cech had a very dodgy opening game against Manchester City and sees it sail just off target.

    Spanish winger Pedro then has a pop but again it does not work the Gunners keeper.

  16. Chelsea 0-0 Arsenal

    Chelsea's Ross Barkley the only Englishman starting the game.

  17. CLOSE!

    Chelsea 0-0 Arsenal

    An effort at goal inside the first 30 seconds.

    Arsenal play a quick move to the edge of the Chelsea box, but Pierre-Emerick Aubameyang strangles a shot straight into the hands of goalkeeper Kepa Arrizabalaga.

    Chelsea v Arsenal (17:30 BST)

    Steve Wilson
    Match of the Day commentator

    The fixture computer could hardly have been less kind to Unai Emery as he starts the task of revitalising Arsenal. Having lost to Manchester City they face a trip to Chelsea - where they have scored only once on their last six league and cup visits.

    "Our players need to improve in the biggest games" said Emery in his press conference on Thursday. "Tell us something we didn't know", the Arsenal fans might have been thinking.

    Last season Arsenal took only six points from their 10 league games against the top five, winning only once - just not good enough.

    Chelsea looked accomplished in their win at Huddersfield last weekend, and with Mateo Kovacic to throw into the mix they shouldn't be short of midfield creativity. However, getting Alvaro Morata to up his goal-rate continues to be a priority.
