The 29-year-old cited "racism and disrespect" as a key reason behind his decision to end his global football career having won the World Cup in 2014.
The new Arsenal manager Emery might have hoped for a more straightforward assignment as he spoke to the media for the first time in south-east Asia but the morning was overshadowed by the continuing furore surrounding Ozil's decision.
"As a team we support him here, we try to make sure he feels good, so he can train and perform at his best".
Unai Emery said in the past that he was going to rejuvenate Mesut Ozil in the upcoming season as he hopes that the German global will be at his best in his first season because he hopes that it could be a success.
Ozil joined the Arsenal squad in Singapore for pre-season training, before they face Atletico Madrid in a friendly on Thursday.

Mourinho then listed out a couple of examples, probably in anger, as he stated that he wanted to play all the pre-season matches in Los Angeles.
He said in Ankara it's "truly unacceptable that a young man who has given everything to the German national team and has contributed to its success is facing such a racist attitude because of his religion".
"I am German when we win, but I am an immigrant when we lose", Ozil wrote, adding: "Certain German newspapers are using my background and photo with President Erdogan as right-wing propaganda to further their political cause".
The German football association has rejected Ozil's claims of racism.
Ozil has not commented about his decision since his arrival in Singapore on Monday with Arsenal.
'He has experience, he has quality and he has a great mentality and we are going to help him feel good and to show his quality with us. "It's a test for us to get ready for the new season, so it's something to look forward to".
