Sagna with a risky challenge on Obertan in a dangerous area.

Arsenal continuing with the patient approach - they found joy after enticing Newcastle up the field, after all. Oxlade-Chamberlain with a heavy cross sees an opportunity spurned.
Newcastle will try to regroup now. They will feel hard done by but Santon played Walcott onside and there's no way back against the speedy forward when that happens.

Newcastle kick-off and we are underway.
Thanks for your feedback. The players are on the pitch and we will be underway shortly.
Newcastle's injury problems are indicated by the fact that their bench includes youngster Mehdi Abeid.
Theo Walcott continues in attack for Arsenal. He can discuss terms with foreign clubs about a Bosman free transfer in the summer from next week.
James says: "Easy win for Arsenal. Newcastle not in good form. 3-0 win for the Arsenal."
Harry: "I am going 2-1 to Arsenal with the team they have put out! Cisse to score for Newcastle and Cazorla and Wilshere for Arsenal!"
Pete: "I think Newcastle could have done with Ben Arfa and Cabaye fit to contend with the Arsenal midfield - but I can see a hard-fought draw with Collocini and Tiote having strong games to contain the young Arsenal players."
Ant on Twitter: "Going for 3-1 Arsenal. Ba will open the scoring then two goals from Walcott and one from Cazorla will win it for Arsenal."
Chris on Twitter: "Wenger gone for the team I would start, allowing Arsenal great speed, finishing and creativeness all at same time."
The last time Newcastle had fewer points after 19 games in the top-flight was 1988-89 (17). They were relegated at the end of that campaign.
It's not doing Alan Pardew's men much good. Newcastle are 10 points worse off than they were at this point last season.
There could well be a contrast in styles here. Newcastle have played the highest proportion of long passes this season (17%), Arsenal the second lowest (8%).
Mikel Arteta has made an average of 87 passes per game this season, more than any other player.
Aron says: "Hello from a sunny festive holiday in Sharm-el-sheikh. As a Newcastle fan I should really back my team every week. However, seeing some performances this season I can't predict a Toon win today so I'm going for a 3-1 Arsenal win with Obertan scoring for the Magpies..I hope I'm wrong but can't see it happening!!"
Arsenal have only won four of their last 11 Premier League home games (W4 D4 L3). But statistics can be funny things. The Gunners have also won their last three Premier League games, the joint best current run in the division (along with Chelsea) going into the weekend.
Robert on Twitter: "I think Arsenal's winter break will prove too much of an advantage today. 3-1 Arsenal. Hope i am wrong though."
Danni says: "Predict another attacking display by the Toon. Season will be kickstarted this evening - Ba and a Cisse double in a Toon 3-1 victory."
Arsenal: Szczesny, Sagna, Koscielny, Vermaelen, Gibbs, Arteta, Wilshere, Oxlade-Chamberlain, Cazorla, Podolski, Walcott.
Newcastle: Krul, Simpson, Perch, Coloccini, Santon, Bigirimana, Tiote, Cisse, Marveaux, Obertan, Ba.
The teams are in and will be up shortly.
