Crystal Palace start the second half having come out early following the break.
Well it was always going to be a little bit backs-to-the-wall stuff for struggling Palace, but they coped well in the main with a slightly disjointed Arsenal and could have really upset things if Chamakh had latched onto that cross towards the end of the first half.

More possession for the Gunners, who find Ramsey on the right but Palace do well and win a throw in off Sagna.
Palace haven't been able to put many passes together just yet, but it was hard to envisage anything other than that beforehand. The home side will have to make the most of it when able to send the ball forward.

Kam Rayat: "Arsenal to win 6-0. Özil to score 1st."
Chris Sergio writes: "Crystal Palace using the 'Christmas tree formation'! I haven't seen this used since 1986! love it!"
Jordan Green says: "Arsenal will win comfortably 1-3, Giroud twice and Özil to score. P.S. I'm not an Arsenal fan."
The players are in the tunnel ahead of the game and here's hoping for an entertaining encounter. The Premier League has a habit of throwing up some huge surprises so nothing can be ruled out, but it's clearly going to be difficult for Crystal Palace.
Scott Greene is straight to the point with: "4-0 Arsenal Giroud to score first."
Lewis Rodders from Chester has this to say: "I think Crystal Palace will put up a real fight today but Arsenal will be too strong. I'm going for an Arsenal 2-0 win with Giroud first goalscorer."
Kevin Hall writes: "'Lads it's not a real game today so let's get it sorted and close up', could be the mindset which may pay the price IF Palace can hold them out 'til half time. Then the Gunners get frustrated and into a tizzy as each minute ticks by after 60. Just one scenario of encouragement for the home team. Otherwise, a 0-1 result is likely."
Having had a quick glance at Sky Bet's Price Boosts, I'm going for Mesut Ozil to score first and Arsenal to win 2-0, which can be backed at 40/1! Don't forget to get your predictions in to firstname.lastname@example.org.
Six changes for Palace from the side that slumped to a 4-1 defeat to Fulham, with Jerome Thomas, Barry Bannan and former Arsenal man Marouane Chamakh among those brought in by Millen. Danny Gabbidon is preferred to benched Adrian Mariappa at centre-back.
So Jack Wilshere is on the bench after picking up another knock on that troublesome ankle in midweek and it will be fascinating to see how Ozil and Cazorla operate together, presumably starting on the right and left respectively, with Flamini, Arteta and the goal machine that is Aaron Ramsey in the middle.
Arsenal team: Szczesny, Sagna, Koscielny, Mertesacker, Gibbs, Arteta, Flamini, Ramsey, Cazorla, Ozil, Giroud. Subs: Fabianski, Vermaelen, Monreal, Rosicky, Wilshere, Gnabry, Bendtner.
Crystal Palace team: Speroni, Ward, Delaney, Gabbidon, Moxey, Jedinak, Dikgacoi, Bannan, Thomas, Guedioura, Chamakh. Subs: Price, Mariappa, O'Keefe, Puncheon, Kebe, Bolasie, Gayle.
Sky Bet report Arsenal to be one of the best backed teams of the day. The Gunners are unbeaten in their last 13 away matches and are odds-on to extend that run against a Palace side who have drifted from 6/1 to 10/1 to claim only their second win of the season. Olivier Giroud, who has been Price Boosted to 4/1 (from 7/2), is hugely popular to break the deadlock for the third time away from home this season in the first goalscorer market. Head to Sky Bet to place all your pre-match and in-play football bets.
Crystal Palace start life without last season's hero Ian Holloway at the helm and Keith Millen is the caretaker manager for the time being. It could hardly be a worse time to be facing Arsene Wenger's table-toppers, who will be looking to bounce back from a midweek defeat at home to Borussia Dortmund in the Champions League. Last time these two teams met in the top flight Arsenal romped to a 5-1 victory, while Palace haven't beaten the Gunners at home in any competition since 1979. So I presume everyone expects a comfortable away win, right?
We'll be bringing you the team news as soon as we have it but in the meantime please send in your thoughts and predictions to email@example.com and I'll post as many as possible before the match begins.
