Flamini and Lamela both make debuts after coming off the bench
Wilshere forced off before half-time with an injury
Arsenal 1-0 Tottenham (Giroud)
18.15: That wraps up our coverage of today's football and we may have only seen two goals but they were extremely important ones. Liverpool sit pretty at the top of the league, while Manchester United are now down in seventh. Arsenal showed they can be a force but even Aaron Ramsey admits they need reinforcements and it seems Tottenham's squad will need time to gel. Join us tomrorow for live coverage of the final day of the transfer window. Should be fun.
18.08: Andre Villas-Boas: "It was a competitive game, we both had chances. It really changed in the second half. For them to finish with four full-backs says much about our domination.
"It was great spirit from our players to approach the game in such a courageous way in the second half. To expose Arsenal in that way is a great example for us.
"We don't have time for the players to gel. We played on Thursday and again on Sundays, we don't have enough time at this moment to put the team together."
18.04: Aaron Ramsey admits Arsenal need some depth in their squad saying:
"The manager has recognised that and he is trying to bring in some more players but he has stuck by us."
17.53: Arsenal 1-0 Tottenham: So it is only Liverpool who can boast a 100% record in the Premier League after Tottenham suffer their first loss. Arsenal move up to fourth with that victory and perhaps Wenger will feel this squad is good enough to compete for trophies.
17.52: Walker with a Rory Delap-esque long throw but Arsenal get a free-kick and that's it. It's all over and Arsenal claim a vital win over their big spending local rivals. A massive result for Arsene Wenger.
17.50: Tottenham are throwing everyone forward and they have a chance to get the ball in the box after winning a late corner. There is plenty of confusion but it falls wot Walker who swings and barely connects with the ball. All hands on deck for Arsenal.
17.47: We're going to have five minutes of injury time but you just can't see Tottenham getting a goal. Their latest effort is from Kyle Walker but his long range shot is both high and extremely wide.
17.44: Spurs really struggling to create any chances. I wonder if they'll regret only signing one striker this summer.
Spend £100-odd million on midfielders and forwards and haven't scored a goal from open play in three league games... #Bale— Brad Pinard (@Brad_Pinard) September 1, 2013
17.43: Lamela with his first effort on goal, but after a clever turn on the right of the box, his left foot effort is rather tame and easy for Szczesny. Time running out for Spurs.
17.41: With less than seven minutes remaining it is Arsenal who remain the most dangerous. Walcott, Cazorla and Giroud are linking incredibly well and they look so dangerous whenever breaking at pace. Tottenham just haven't got going at all.
17.36: CHANCE: Monreal could have scored with his very first touch after terrific play from Giroud. The big striker goes on an impressive run before cutting the ball back to Walcott. His shot is well saved but any sort of good contact from Monreal and he doubles the lead. However, he can't quite wrap his foot around the ball and Spurs survive.
17.35: Rosicky makes way and left-back Nacho Monreal comes on to try and help Arsenal hold on to their lead.
17.32: SAVE: Brilliant reaction save from Szczesny as Defoe's shot from the esge of the box deflects off Koscielny and the Polish stopper gets a strong hand to the ball to keep it out. Tottenham continue to press and they are certain the ball hit the hand of an Arsenal player but the referee disagrees.
17.31: Tottenham need to show a bit of fight here, so who better to bring on than Sandro....
17.29: Etienne Capoue looks in absolute agony after Cazorla fell on his ankle. It doesn't look good for Tottenham's new signing. However, it means we will see the return of Sandro and record signing Erik Lamela.
17.25: It's Dembele that makes way for Defoe. Can he get that all important equaliser?
17.23: Spurs are desperate for a goal and it seems they feel Jermain Defoe may be the man to deliver. The England striker is stripping off and will soon be on.
17.20: Tottenham enjoying the lions share of possession in the second half but Arsenal look so dangerous on the counter. This time Cazorla, Walcott and Giroud combine before the Frenchman's stinging effort is turned round the post by Lloris.
17.15: Walcott is certainly looking dangerous today and Danny Rose is struggling to stop the England winger from getting his crosses away. Luckily for Tottenham he can't pick anyone out and Spurs survive.
17.11: Yellow Card: Flamini has only been on the pitch about 10 minutes but he has already picked up his first booking courtesy of a meaty challenge on Danny Rose.
17.09: AVB looks a little concerned on the touchline. His powerhouse midfield is getting overrun and the wide players simply aren't seeing enough of the ball. I wonder if this game just came a bit early for all the new signings.
17.06: Wilshere ha been suffering from stomach cramps it turns out so no recurrence of an old injury. That's good news for Arsenal and England.
17.04: Quick update on Glen Johnson who picked up a knock in Liverpool's win earlier today. Seems he'll have a scan tomorrow.
Thanks for all the nice messages. My ankle feels bad at the mo but i have a scan tom morning. So fingers crossed!— Glen Johnson (@glen_johnson) September 1, 2013
17.02: We are back underway and Spurs can't call on Gareth Bale to come up with an all important goal but perhaps Erik Lamela can make a big impact if he comes off the bench. He'd definitely make himself an instant favourite if he could grab an equaliser.
16.53: Great first half for Arsenal then but Wilshere picking up another injury will be a concern.
Real shame that Wilshere is so prone to injury. So talented but shows how fragile footballers careers can be.— Gary Lineker (@GaryLineker) September 1, 2013
16.46: That's half time and it's been an enjoyable one if you are an Arsenal supporter. Spurs have been a little too tentative in possession and Cazorla, Arteta and Rosicky have taken control of the centre of the park.
16.43: Flamini returns - Jack Wilshere is clearly struggling as he gingerly moves around the pitch and with minutes to go until half-time he is taken off as Mathieu Flamini makes his second debut for the Gunners.
16.40: It's another positive run from Townsend as he once again cuts inside and gets his shot away. It's another good effort but it's a comfortable save for Szczesny.
16.36: Spurs are really struggling to get their wideboys Townsend and Chadli on the ball. Both looked dangerous early but Arsenal have started to dictate the play and look dangerous whenever they advance at pace.
16.32: Brilliant piece of goalkeeping from Lloris who is quickly off his line to make a perfect last ditch tackle on Theo Walcott. The French keeper had to get a touch on that or else he would have been off.
16.31: Arsenal go straight up the other end and Aaron Ramsey has a chance to extend Arsenal's lead but his left foot shot from the edge of the area balloons over the bar. End to end stuff.
16.30: Cracking effort from distance from Townsend who loves to cut inside and shoot with his left foot. This one would have snuck in the bottom corner had Szczesny not got down well to keep it out.
16.27: That goal has really helped the Arsenal players settle. Walcott is making some intelligent runs and Giroud's movement off the ball has been very good. Perhaps he's showing Wenger why the Frenchman doesn't need to sign another striker.
16.25: Arsenal fans in fine voice here but as we mentioned, taking the lead in this game does not always guarantee a victory.
16.23: GOAL: Arsenal 1-0 Tottenham - Olivier Giroud
Brilliant counter attack from Arsenal who break at great pace and Theo Walcott finds space down the right channel, his ball finds Giroud who steers the ball past his international teammate Hugo Lloris. Great start for the Gunners.
16.21: I'm sure neither set of supporters need reminding but just in case, the last two games between the two sides here at the Emirates finished 5-2 to Arsenal, with Spurs taking the lead on both occasions.
16.19: Another corner for Tottenham is easily cleared but the Villas-Boas' side are certainly seeing plenty of the ball early on here.
16.15: The camera's turn to David Beckham in the stands who is celebrating his son Romeo's birthday by attending the game today. Wonder who old goldenballs wants to win.
16.12: I'm expecting goals here today at the Emirates and according to Opta we should all be in for a treat. It's even at the minute as Etienne Capoue and Paulinho certainly look like an impressive partnership for Spurs.
124 - There have been 124 goals scored in @premierleague meetings between Tottenham and Arsenal; more than any other fixture. Galore.

16.06: Another great opportunity to test Lloris. Another free-kick is given but this one is more central and a good distance out. Cazorla again and it goes along the deck and just past the post. That was close. 16.05: Walker and Towsend really do offer Spurs some serious pace down the right. Gibbs may well be in for a tough day. 16.03: Olivier Giroud then fails to trouble the French keeper from the resulting corner despite winning the header. 16.02: Just two minutes in and now Arsenal have a chance as Capoue brings down Rosicky. Santi Cazorla fires and it's a fine save from Hugo Lloris. 16.01: Early corner for Spurs thanks to a direct run from Andros Towsend who flew past the jet heeled Kieran Gibbs. The cross isn't great though and Arsenal safely clear their lines. 16.00: Peep, we are underway at the Emirates. We have the oldest Premier League manager against the youngest. Will the young pretender trump the old master? 15.58: This really is a huge game and I wonder which set of supporters will have the bragging rights come 6pm. You have to say Spurs have an extremely strong bench, I wonder if that will play a part. 15.55: Having seen Liverpool gain another 1-0 win, can Tottenham repeat that trick as well. Roberto Soldado with a penalty anyone? 15.50: There have been plenty of goals in this fixture in recent seasons but what are the odds on there also being a sending off.
2 - There has been a Tottenham player sent off on each of their last two Premier League visits to The Emirates. Feisty. — OptaJoe (@OptaJoe) September 1, 2013
15.41: So no first start for new signing Erik Lamela but Tottenham's new record signing is on the bench. For Arsenal the returning Mathieu Flamini is also on the bench, as are exciting young German duo Serge Gnabry and Gedion Zelalem.
15.38: Team news.
Arsenal: Szczesny, Jenkinson, Mertesacker, Koscielny, Gibbs, Wilshere, Ramsey, Walcott, Rosicky, Cazorla, Giroud. Subs: Sagna, Monreal, Flamini, Fabianski, Sanogo, Gnabry, Zelalem.
Tottenham: Lloris, Walker, Dawson, Vertonghen, Rose, Capoue, Paulinho, Townsend, Dembele, Chadli, Soldado. Subs: Lamela, Holtby, Naughton, Defoe, Sigurdsson, Friedel, Sandro.
Referee: Michael Oliver (Northumberland)
15.36: If you missed the Liverpool game and want to see exactly what happened then simply click here.
15.35: Attention now turns to the Emirates after an exciting game at Anfield which saw Liverpool secure their third 1-0 win of the season thanks to another goal from Daniel Sturridge. That victory over Manchester United means the Reds have won their opening three games of the season for the first time since 1994 and they now sit top of the table.
