The Gunners playmaker announced his retirement from worldwide football on Sunday, citing discrimination from the DFB as part of the reasoning for his decision.
Ozil criticized the German football federation, its president, fans and media for what he regarded as racism in how people with Turkish roots were treated.
"Everybody at the club is thinking like me to help him and to feel (good) here and express his quality with us".
Many politicians and journalists in Germany questioned Ozil's loyalty to his country after photographs emerged of Ozil, a third generation immigrant with a Turkish heritage, posing alongside Erdogan.
"I am very happy with him, every player is looking together and Mesut has the respect of every player here".
Arsenal open the new Premier League campaign with a home fixture against champions Manchester City on Aug.12.
"He feels here with us that he can work every day, and it is good for us that he made a decision to come here and work with us before our two matches".
"It´s something which is unfortunate for him but we will try to do everything so that he feels good, that he trains well so he feels good for the season, because he´s one of the key players".
"Normality is the best thing for him and I am sure he´s going to do a big season with us this year.it´s very, very personal and here I want to help him".
Ozil has not commented about his decision since his arrival in Singapore on Monday with Arsenal.
Goalkeeper Petr Cech, who insists he is "concentrating on this season" amid speculation about his long-term future at the Emirates Stadium, is also keen to support Ozil as a colleague and to avoid assuming a position in his argument with the DFB. He's played at global level, and he's a key player for us so yes he's one of the candidates. As a team that's all we can do.
