Bournemouth, on the other hand, are in sixth place in the top flight and trailing Arsenal by four points following a run of three victories in their last six games.
More has perhaps been expected of a player who cost the Gunners a fee in the region of €50million five years ago, and Emery has promised to make the most of the World Cup winner's natural ability.
Emery has made changes defensively, deploying a higher and more aggressive pressing game that has been adopted surprisingly quickly by his players. We want (to finish in the top four) but it's not easy.
Bournemouth and Arsenal have been operating at very different ends of the football pyramid over the years but Sunday lunchtime's Premier League fixture sees the team ranked sixth in the table host the side now occupying fifth place.
Emery told Spanish newspaper Marca in an interview this week that one of his main tasks was to rebuild Arsenal's defensive structure without losing the focus on attacking football that Arsene Wenger brought to the club.
"Before Wenger arrived, Arsenal celebrated the 1-0 (win) and was based on defensive solidity".
Both sides will be looking to register a when they face off in English Premier League..
"But over time, only technical quality and offensive freedom were taken care of, and the team lost the defensive structure". I respect him a lot, but no matter how much info he gave me, I had to change things. "We had to stop that and start climbing".
Arsenal travel to Bournemouth on Sunday, hoping to break a run of three consecutive draws in all competitions.
And when asked what exactly needs to improve specifically, Emery said: "Everything". He is well, with good performances, good feeling and I think he is close to also playing with us.
Emery's side play Tottenham twice, Manchester United and Liverpool in December.
"We need more in some things, being different tactically, individually, in the spirit, in the mentality".
