Arsenal 3 Newcastle United 0
NEWCASTLE United were easily beaten tonight at the Emirates Stadium as Arsenal ran riot in the capital.
Goals from Robin van Persie (2) and Denilson won it for the Gunners on a night when Newcastle just weren't at the races.
To cap off a miserable day for Newcastle Joey Barton was roundly booed by the home fans on his return to the game after a stretch in prison.
Keegan paired Michael Owen in attack with Shola Ameobi with the Academy product back from a hamstring problem sustained in pre-season.
Owen was starting his first match of the campaign and donned the skipper's armband in front of the watching Fabio Capello.
Jose Enrique kept his place after the Carling Cup win at Coventry with Charles N'Zogbia staying on the left wing.
Jonas Gutierrez started wide right after his stint as a striker at the Ricoh Arena.
And on the bench Keegan named Joey Barton with the controversial midfielder yet to taste any action this season following his stretch in prison.
Newcastle - cheered on by Mike Ashley in the away section - escaped penalty appeals from the home side with just two minutes played when Fabricio Coloccini sent Robin Van Persie tumbling but Rob Styles waved away protests.
Arsenal then missed a golden chance after the Dutchman's corner was flicked on by Bacary Sagna and found William Gallas at the back stick but the French defender somehow sent it high over the bar right in front of goal.
On six minutes Given was on red alert again when Kolo Toure's forward run and shot was diverted wide of the post by the Irish keeper.
In the 17 th minute Van Persie's right footed effort near the edge of the area flashed wide of the post as Newcastle survived.
But Arsenal were handed a penalty moments later.
Emmanuel Adebayor's left wing cross struck the hand of N'Zogbia and Van Persie blasted it to Given's left to open the scores even though the Irishman had guessed the right way.
Adebayor was then tripped by Coloccini near the D and after the South American was booked by Styles on 29 minutes Cesc Fabregas could only hit the Toon wall.
Arsenal won another set-piece following Van Persie twisting run on the half hour mark following Beye's slight challenge on the Dutchman and this time United had to rely on Given to push the ball over the bar.
Nine minutes before the break came Newcastle's first glimpse of goal after Gutierrez's right wing cross but even though Owen had time and space at the back post he could only steer it off the heels of strike partner Ameobi with ball squirting wide.
United were made to pay four minutes before the interval as Adebayor slid the ball across to Emmanuel Eboue who had time to backheel the ball into the path of Van Persie who pounced to make it 2-0.
Newcastle made a change before the break with Sebastien Bassong replacing Enrique at left-back after enduring a torrid time first half against Adebayor in and around the left right channel.
United went in for the interval looking for a miracle in the second half with Arsenal in full control at the break.
Five minutes into the second half a Denilson foul on Guthrie handed United a free-kick deep on the right but N'Zogbia's woeful effort sailed harmlessly into the crowd.
Nevertheless Newcastle enjoyed the best of the possession at the start of the first half and after the Mags had won a corner N'Zogbia's flag kick found the head of Nicky Butt who crashed an effort off the bar with Arsenal failing to clear their lines on 55 minutes.
Seconds later and N'Zogbia rolled a ball across the final third and Guthrie's low effort had to be gobbled up by Manuel Almunia for Newcastle's first shot on target.
But it was 3-0 and game over before the hour mark as Arsenal bagged number three.
Bassong's half clearance on 59 minutes was intercepted by Nasri who picked out Adebayor before Denilson ghosted in to fire past Given who was rooted to the spot.
On their next attack two minutes later Van Persie's powerful effort crashed off the frame of the goal with Arsenal quickly getting back on top of the game.
Van Persie then hobbled off with a knock and while Newcastle were glad to see the back of him the damage was done.
Adebayor took over from that point onwards for the Gunners and after waltzing through again Steven Taylor's bodycheck earned Arsenal a free-kick on the edge of the penalty area.
Nasri curled it towards the top corner but Given bailed United out again with a top class save.
