Pires, who was part of Arsenal's Invincibles side that went 49 games without defeat and clinched the title in 2004, believes Emery is fully vindicating the Gunners' decision to appoint him as Arsene Wenger's successor.
The Gunners will resume Premier League action following the global break with a trip to Bournemouth on Sunday, looking to extend a 16-match unbeaten run in all competitions.
Getting Arsenal back into the Champions League is manager Unai Emery's main goal, but the Spaniard said on Friday it won't be an easy job as the competition for a top-four finish in the Premier League is tough.
Maybe we won't reach those heights this season, but I do like his ambition to get us right to the very top!
"Before Wenger arrived, Arsenal celebrated the 1-0 (win) and was based on defensive solidity".
"But over time, only technical quality and offensive freedom were taken care of, and the team lost the defensive structure".More news: Minutes After Wishing Everyone Happy Thanksgiving, Trump Criticizes Chief Justice John Roberts

"I am delighted with the treatment of the club in all areas, but I want them to be demanding of me because I will then push the club forward". "I respect him a lot but, no matter how much information he gave me, I had to change things". The Arsenal was in decline.
"I told the players: 'We are starting at ground zero.' Even now, four months later, I still say we are just at the beginning". Arsenal were falling. We had to stop that and start to lift them.
"Two years later, they were in the final of the Champions League". He is well, with good performances, good feeling and I think he is close to also playing with us.
The Gunners have failed to qualify for Europe's elite club competition for two seasons in a row having finished sixth and fifth respectively in their last two league campaigns.
And when asked what exactly needs to improve specifically, Emery said: "Everything".
Emery's side play Tottenham twice, Manchester United and Liverpool in December.
