Emery was brought in by the Gunners this summer and given the unenviable task of replacing managerial stalwart Arsene Wenger, who had presided over events in North London for an incredible 22 years.
"The Premier League is our priority, and our objective in terms of the table is to finish in the top four", Emery told the club's official website.
Emery said: "I respect Wenger a lot, but no matter how much information he gave me, I had to change things".
"I forget also, Stephan Lichtsteiner is beginning to train with us but he is maybe not okay for Sunday".
"Before Wenger arrived, Arsenal celebrated the 1-0 (win) and was based on defensive solidity".
"What I want is to unite both aspects and be more competitive". But the last three we have drawn. Arsenal fans are coming to know a man as relentlessly obsessive as the pre-season rumours had them believe, and it is also becoming increasingly clear that Emery is a coach who takes pleasure from life's challenges. The Arsenal was in decline. "We had to stop that and start climbing".

Footage also emerged of the Boca bus approaching the stadium at high speed, trying to avoid the barrage from the River Plate fans. Second, physical injury was suffered by at least two Boca players as a effect of splinters of glass from the broken windows.
"That's a good example for us - maybe we can not do the same, because it's very very hard and they worked very well with [Jurgen] Klopp in this progression".
Emery's side now sit fifth in the Premier League, three points off the top four, and they could make it 17 games without defeat against Bournemouth on Sunday.
"I am knowing every day, the competition better".
"We had to rearrange the furniture, and not because of anything bad that happened previously, but to stimulate everyone again - to shake things up, sweep under the carpets, open the windows - in a positive way".
Arsenal manager Unai Emery says he is constantly challenging Mesut Ozil to produce high-quality performances on a more consistent basis.
"We'll see if we can finish with some trophies. His energy levels... We had dinner with him on Wednesday and his energy and passion is infectious".
Mavropanos is also still out, but we should have enough choices at the back with Sokratis, Mustafi and Holding available, and Bellerin and Kolasinac (or Maitland-Niles) to cover for the wing-backs.
