Emery admitted Ozil's first worldwide break since his retirement will have been a hard adjustment for the player, but that the pair have been able to spend beneficial time on the training ground together.
Emery on Mesut Ozil's mindset: "Every day with us I look at him and he looks well and happy, working with our demands".
"We are continuing our process with our positive things and our work".
However, he returned for a 3-2 win away to Cardiff before the worldwide break and is expected to keep his place for the trip to St James' Park.
'I'm sure lots of top clubs are monitoring the situation and are ready to poach him.
"They can play a counter-attacking game, and a possession game, because they have enough quality". We were missing a chance, and then maybe they would score.
The manager added: "Saturday is another step we can do, it will be hard but I want to continue [to show] our personality on the pitch and impose this personality on the opposition and to find the win".
"Sometimes you can have all of the tactics right and one player can make the difference". Things like that can happen in every game, and that's why football is so hard.
Arsenal's two victories in their last three away games are the same as in their previous 13 games before that, with the Gunners yet to win consecutive away games since May. "And I want to push every player to be okay to help the team if for one minute, 30 minutes or half time or 90 minutes".
You never know because your body, sometimes you start with some problems, some injuries and you can't continue giving 100 per cent.
