Emmanuel Adebayor believes Arsenal can make a serious challenge for silverware if they show the quality and spirit that swept aside Newcastle 3-0.
Arsene Wenger's side made a spluttering start to the campaign but they followed last Wednesday's demoliton of FC Twente with another impressive display at the Emirates Stadium.
Adebayor, restored to the team after being rested by Wenger in midweek, played a key role as he set up two of the goals on Saturday and the Togo striker is convinced the Gunners are firing on all cylinders again.
"I believe in our quality and I think we got our fans back with this performance," Adebayor said. "When we all play together like that and show our spirit we have a chance to win.
"It was very important to show that. If we play like this we have a lot of chances to win something."
Robin van Persie who opened the scoring with an 18th minute penalty after Charles N'Zogbia handled Adebayor's cross, the AFP reported.
Arsenal were in complete control and increased their lead in the 42nd minute with a typically flamboyant goal. Adebayor was the provider with a neat backheel to Van Persie, who lashed home from close-range.
Denilson underlined Arsenal's superiority when the young Brazilian midfielder flicked home from close range on the hour for his first Premier League goal.
Paul Ince suffered a miserable return to West Ham as Blackburn were thrashed 4-1 at Upton Park.
Rovers boss Ince, a former West Ham midfielder, must have known it wasn't going to be his day when Calum Davenport scored with a powerful header from a 12th minute corner.
Christopher Samba's own goal made it two before Jason Roberts gave Blackburn a lifeline in the 22nd minute with a fine turn and finish.
Carlton Cole handled Steven Reid's free-kick in the West Ham area early in the second half but Roberts's penalty was well saved by Robert Green.
That was the turning point as Craig Bellamy's late goal killed off Rovers before Cole's 90th minute strike added to Ince's agony.
The victory eased the pressure on Hammers boss Alan Curbishley, who said: "I've been around long enough to know that when the vultures are around it gets difficult.
"I've never had it before but you just have to deal with it. I'd rather it was directed at me than the players."
Portsmouth won for the first time this season as Jermain Defoe's double-strike clinched a 3-0 victory over Everton at Goodison Park.
Peter Crouch's partnership with Defoe finally sparked into life in the 12th minute. Crouch flicked on a long punt and Defoe worked space to drive home a low strike for his first goal in nine games.
Johnson played a one-two with Defoe and surged into the penalty area before flicking a sublime finish past Tim Howard.
David James preserved Portsmouth's two-goal lead early in the second half when he saved Ayegbeni Yakubu's penalty. Defoe put the result beyond doubt in the 69th minute.
Redknapp said: "Jermain was great. The goals were two excellent bits of skill from a top-class striker.
"We worked hard on our system all week and getting this result should give the players a lot of belief."
