Full-time: Newcastle United 0-1 Arsenal
- Aleksandar Mitrovic sent off in the first half for Newcastle
- Arsenal denied a clear penalty following Florian Thauvin's challenge on Hector Bellerin
- Fabricio Coloccini deflects Alex Oxlade-Chamberlain's shot beyond the reach of Tim Krul for the winning goal
- Newcastle still searching for their first league victory under Steve McClaren
So there ends a volatile affair in which Newcastle huffed and puffed but were always battling against the odds following that costly early bout of ill-discipline that saw Mitrovic dismissed.
Arsenal were more than comfortable in the end and Cech was very rarely called into action throughout the 90 minutes. However, one deflected goal to show for their dominance and plethora of shots is another worrying return and will only increase calls for Wenger to invest in a new striker over the coming days.
That is it for this particular live blog, but click here to follow coverage of this afternoon's 15:00 BST Premier League kick-off's including Chelsea v Crystal Palace and Liverpool v West Ham. See you there.
Newcastle 0-1 Arsenal
A late chance for substitute Giroud goes begging as Krul makes a very unconventional save. That is it.
Coloccini is now the sixth player to enter the referee's notebook following a strong challenge on Coquelin. Looked harsh, that.
Three minutes of added time signalled by the fourth official. Can Newcastle muster a late response or are Arsenal on for their second away victory of the season?
Janmaat deflects Sanchez's shot behind. Monreal then tries his luck from the resulting corner but Krul holds comfortably.
Arsenal playing keep-ball now, content to work it around and wait for an opening rather than invite any unnecessary pressure on the counter-attack.
Newcastle will have to take a risk here if they are to avoid defeat, you feel. A final throw of the dice from McClaren as Siem de Jong comes on in place of Thauvin.
Five minutes plus added time remaining.
10 minutes remaining and Oxlade-Chamberlain is replaced by Mikel Arteta. The former looked to be limping a little bit there as he made his way to the bench.
Giroud nods Cazorla's corner across goal but Sanchez is unable to get a clean shot away.
Krul then saves a low shot from Giroud before racing off his line to deny the rampaging Sanchez.
Papiss Cisse on for Newcastle in place of Sissoko.
Giroud's first real involvement in proceedings is to send a shot high over the crossbar following good work from Sanchez.
McClaren has made his first substitution of the afternoon, introducing Perez at the expense of Anita.
Giroud is now on in place of Walcott, who will have done little to appease Arsenal supporters who remain certain that Wenger needs to sign a marquee striker before Tuesday's transfer deadline.
Another chance for Arsenal as Ramsey and Oxlade-Chamberlain work a shooting angle for Cazorla who stings the palms of Krul.
Walcott is playing out on the left flank now with Oxlade-Chamberlain joining Sanchez in the middle. Giroud preparing to enter the fray.
Newcastle carved open down their right-hand side as Sanchez and Monreal combine to good effect. The Spaniard provides a low ball for Oxlade-Chamberlain, who can only send his shot wide.
That effort will likely go down as an own goal given that Oxlade-Chamberlain's shot looked to be drifting wide before it struck the unlucky Coloccini.
Sanchez comes close to doubling Arsenal's lead shortly before the hour-mark after being set-up by Ramsey but Krul makes a smart save.
Arsenal finally take the lead and it's a little harsh on Newcastle. Ramsey's shot is parried by Krul and Oxlade-Chamberlain takes the rebound on his chest before firing home via a huge deflection off the foot of Coloccini.
Goal: Newcastle 0-1 Arsenal (Alex Oxlade-Chamberlain)
Yellow cards are being showered around like confetti at St James' Park as Cazorla is the first Arsenal player booked for a challenge on Georginio Wijnaldum and the latter is cautioned for his angered reaction.
Two minutes after the break and Newcastle have another player in the book. This time Vurnon Anita is punished following a tussle with Sanchez.
The teams are back out and the second half is now upon us. No changes from McClaren or Wenger.
McClaren will be relieved to have gone in at half-time with the score still level after his team demonstrated a worrying lack of discipline throughout the opening 30 minutes and were also very fortunate indeed not to have conceded a penalty.
A lack of goals remains a real concern for Arsenal, who have monopolised possession for the most part, although they are now having to contend with Newcastle wisely packing their 10 men behind the ball.
Newcastle 0-0 Arsenal
An acrobatic effort from Oxlade-Chamberlain comes to nothing and the half-time whistle sounds.
To their credit, Newcastle are beginning to come into this a little following a very poor start. Thauvin looks a threat when he picks up possession on the counter and suave centre-back Mbebma, known for his habit of showing up to matches in a tuxedo, has just launched a driving run from the heart of defence.
