That's the full-time whistle at the Emirates and it's finished Arsenal 5-0 Leyton Orient. The Gunners will progress to the last eight to face Manchester United at Old Trafford after securing a win that never really looked in any doubt. A hat-trick for Bendtner will have done wonders for the Dane's already inflated confidence as he looks set to fill in for the injured Robin Van Persie in the coming weeks. For Russell Slade's Orient, it's Notts County on Saturday as their 13-game unbeaten run comes crashing to a halt. It's been a superb effort to get this far by the League One side and their fans, who were vociferous as they were good humoured all night, will take a lot of pride from their side's glorious cup run. That's all from me this evening, thanks so much for joining Goal.com for tonight's clash. Be sure to catch all of the post-match reaction on the site as it comes in and join us at the weekend for our up-to-date coverage of all the big games.
The game is easing down as the official attendance of 59,000 is read out on the tannoy at the Emirates. I'm not too sure about that...this is pre-season friendly pace in front of a pre-season friendly sized crowd.
Orient's fans have, unlike their team at times, been sublime from start to finish and regardless of the result this evening, they won't forget their trip to the Emirates for a long time, that's for sure.
Jack Wilshere is now looking to get in on the act, dribbling past the Orient defenders with consummate ease but he runs into a bit of a cul-de-sac and the Gunners attack breaks down.
Yellow Card Dean Cox
Substitution Alex Revell P. M'Poku
Tottenham's on-loan youngster Jose M'Poku replaces Alex Revell. How he would love to grab a consolation goal for the visitors here.
Yellow Card Gael Clichy
Goal Gael Clichy
GOAL! Clichy makes it 5-0 for the hosts after meeting Eboue's low cross that had been nicely dummied by Chamakh and somehow missed by Jacj Wilshere. Great finish from the substitute and the O's fairytale FA Cup run is coming to an end in the most disappointing way possible.
Nasri has been at the heart of everything since coming on and looks to make it five with a darting run into the box but as he releases, his shot is blocked superbly by Forbes, his spirit the embodiment of that of his teammates, who haven't given up all night.
Seemingly unsatisfied with a 4-0 lead, the hosts are more than willing to rub salt into the wounds of their opponents, with Chamakh showing his skillful side on the edge of the box before spraying a lovely ball out to Henderson. The youngster puts another fine ball in from the left but nothing comes of it.
Subs for Orient too, as the man who got the O's to the Emirates, Jonathan Tehoue comes on alongside Matthew Spring replacing Crowe and McGleish.
What was that I was saying about risking big stars? Jack Wilshere and Gael Clichy replace Arsenal's two most impressive players in Abou Diaby and Nicklas Bendtner. A semi-rapturous reception meets them both.
Substitution Nicklas Bendtner Jack Wilshere
Substitution A. Diaby Gael Clichy
Substitution Scott McGleish J.Kahne Tehoue
Substitution Jason Crowe Matthew Spring
Just before the penalty was taken, the achingly sluggish Tomas Rosicky was brought off for Samir Nasri. Seems a little unusual for Wenger to risk such a massive player in a game that they're winning 4-0 does it not?
...AND HE HAS! GOAL! 4-0 to Arsenal and I'm going to go on record and say that is that. Let's just hope it doesn't become embarrassing for Russell Slade's side now.
Substitution Tomas Rosicky Samir Nasri
Penalty Goal Nicklas Bendtner
PENALTY! Kieran Gibbs, who has impressed all evening, is brought down in the box by Alex Revell after jinking in dangerously from the left. It'll be Nicklas Bendtner with the chance to make it a hat-trick...
Rosicky goes down clutching his head but after a couple of minutes of looking a little dizzy, the Czech looks to have made a full recovery.
Our man at the Emirates, Oliver Yew updates us on proceedings so far in this second half: 'Leyton Orient may be 3-0 down but they are giving it a real go here. They are having some real joy with balls in behind the Arsenal back four and with a better final delivery they could have pulled at least one goal back.'
It's all Orient at the moment and Arsenal are a mess at the back, with Manuel Almunia flapping at consecutive crosses. Maybe, just maybe, there's life in this tie yet.
The visiting fans are enjoying every minute of their trip to the Emirates and Daniels very nearly rewards them with goal, heading a fine effort goalwards but it's just a little too high and bounces off the roof of the net.
Abou Diaby links up well with Marouane Chamakh and using his strength, breaks into the box and is all alone...he can't keep his head though, sliding the ball agonisingly past Jones' right-hand post. It should be 4-0 but the O's are let off.
Orient haven't given up on this one as the visiting midfielders knock it about nicely, presumably with Russell Slade's voice ringing in their ears. Nothing comes from the build-up and Arsenal clear.
Arsenal are just looking to keep the ball in the opening exchanges, waiting patiently to pick their moments. Wouldn't expect a terribly high tempo second half if the opening 3 minutes are anything to go by.
Arsenal get us back underway at the Emirates. It's looking set to be 45 minutes of damage limitation for Russell Slade's side.
Or so I thought...The Orient fans are chanting "we're gonna win 4-3" as the half time whistle goes. At least they have a sense of humour, I would suggest that they are going to need it in the next 45 minutes.
Yellow Card Ben Chorley
That goal, Bendtner's seventh of the season, has surely put the Gunners out of sight now. I'm all for the magic of the cup but even the most optimistic Orient fan would struggle to see a way back into this one.
Goal Nicklas Bendtner
Goal! Bendtner gets another to make it 3-0. There is certainly a gulf between these two clubs but defending like that isn't acceptable at any level, as the Orient defenders, possibly exhausted from nearly an entire half chasing shadows, let Bendtner jink in from the left hand side and know the ball beyond Jones into the bottom corner. Take nothing away from the Dane by the way, a top class finish that one.
Conor Henderson gets a chance to show off his left foot and passes the test with flying colours, delivering an absolute pearler of a free kick from the left but nobody attacks it and Jones gratefully collects.
Dean Cox hit's a great ball into the Arsenal box but Almunia is hardly challenged on his way up to collecting it. Very much a ball out of hope rather than expectation from the O's midfielder.
It's beginning to look a little ominous for the visitors at the moment, with Arsenal holding the ball, keeping possession well and making their League One counterparts work terribly hard. If Russell Slade's don't get their foot on the ball you can see Goliath picking up David and flinging him around for fun.
Incidentally, that's Bendtner's first big involvement in the night, having largely been a passenger down the right-hand side. It's a peculiar position for the Dane and if truth be told, he looks like he'd rather be anywhere else...the ski slopes perhaps?
Goal Nicklas Bendtner
GOAL! 2-0 for Arsenal from Bendtner. Just as Orient begin to take the initiative in the middle of the park, the quality of their illustrious hosts shines through. Keeping possession in the final third, the ball eventually falls to Kieran Gibbs to deliver a superb cross into Nicklas Bendtner and the Dane smartly nods a floating header past Jones's left-hand post. Fantastic header and it's looking like mission impossible for Russell Slade's side now.
Orient are looking to play some superb possession football and you couldn't accuse them of lumping it up and trying to get in the faces of Arsenal. If anything, they may be trying a little too much tiki-taka at moment. If you believe what you read in the papers, the Gunners don't really like it up 'em.
Bendtner gets down the right-hand channel to hit a low ball into Tomas Rosicky but it's a little languid from the Czech midfielder, mistiming his strike and barely getting a touch on the ball. Groans from the home fans.
Almunia doesn't look at all comfortable and it shows again from an in-swinging corner, with the Spaniard just about collecting the ball amongst a crowd of bodies. Orient are growing in confidence at the moment and Arsenal, like their fans, could do with waking up
Ben Chorley has picked up a knock after going in strongly on Marouane Chamakh. He'll be OK to continue but he certainly felt it.
The Emirates is in no way near to capacity but those Gunners that have made the trip out are being treated to a close-up view of the highly-rated Conor Henderson and the youngster isn't disappointing, showing some spark down the left-hand side and had troubled Orient from the off.
Chance for Orient and it's not too far away. Dean Cox is tripped by Emmanuel Eboue and from the resulting free-kick, Daniels is sent away down the left hand side, delivers a fine ball into Revell but the O's forward is at too tight an angle to get his shot on target. Certainly a wake-up call for Arsene Wenger's side.
It's been a remarkably assured response from Russell Slade's side and are unlucky to see a little bit of interchange in the middle of the park break down. Gibbs collects and breaks but it comes to nothing.
Orient have in no way wilted following that early blow and are unlucky to see Daniel's volley blocked amongst a crowd of Arsenal defenders from a corner coming almost immediately after the restart.
Goal Marouane Chamakh
GOAL! Chamakh for Arsenal! Though you wouldn't know it from the crowd... The former Bourdeaux man collecting the ball from Tomas Rosicky after a superb break down the right-hand side from the Czech international, and the Moroccan hits a bit of a scuffed effort off Terrell Forbes and into the far post.
Danger for Orient as Abou Diaby hits a fine-looking effort from the edge of the box but it's very well blocked by former Arsenal trainee Ben Chorley. It's a bright start for the hosts.
After the exploits of Laurent Koscielny and Wojciech Szczesny at the weekend, an early nervous moment for Manuel Almunia is the opposite of what Arsenal need as Kieran Gibbs hits a terrible backpass to the Spanish keeper. He recovered but it's a nervy start for the hosts
Leyton Orient kick us off at the Emirates, with the visitors surely dreaming of a 6th round tie at Old Trafford against Manchester United. Arsenal on the other hand, will be looking to stave off a nightmare defeat.
Orient have consecutive corners but there's no danger in either of them. It's a great way for the tie to finish, with Arsenal on the back foot and the League One side playing til the death.
A final flourish from Orient as Dean Cox breaks through the middle and races past Sebastien Squillaci. The midfielder does all the hard work but fatigue catches up and he ends up wasting his chance with a fairly limp deflected effort over the bar. Impressive work rate from Cox and in fairness, the O's probably deserve a goal, even if it is just for their superb support.
So it's a first ever start for the highly rated Conor Henderson in midfield as young Spaniard Ignasi Miquel also comes into the heart of the hosts' defence alongside Sebastien Squillaci. Orient, who are unbeaten in 13 games in all competitions, start with the hero from this tie's first clash Jonathan Tehoue on the bench once again.
Leyton Orient: Jones; Crowe, Chorley, Forbes, Whing; Cox, Dawson, Carroll, Daniels; McGleish, Revell. Subs: Butcher, Omozusi, Cestor, M'Poku, Spring, Tehoue, Chambers.
Arsenal: Almunia; Eboue, Squillaci, Miquel, Gibbs; Diaby, Denilson; Rosicky, Henderson, Bendtner; Chamakh. Subs: Szczesny, Sagna, Djourou, Clichy, Wilshere, Nasri, Arshavin.
Hello and welcome to Goal.com's live coverage of the FA Cup fifth round replay between Arsenal and Leyton Orient at the Emirates. From Hereford's Ronnie Radford in '72 to Wrexham beating the mighty Gunners twenty years later, this competition is littered with modern day Davids overcoming their illustrious Goliaths but surely Arsene Wenger's side will bounce back from their Carling Cup final loss with a convincing victory over their League One counterparts? If they don't, then we may well have witnessed a giantkilling to overcome the lot. It's a match-up, that either way, promises to be an enthralling prospect.
