Ozil believes the best is yet to come from his new side and thinks he is now in the most competitive league in the world.
The German joined the Gunner's from Spanish giants Real Madrid on deadline day of the summer transfer window for £42.4 million.
Ozil is currently preparing for Germany's two World Cup qualifiers, with only one more win needed to guarantee their presence in Brazil next year.
The 24-year-old has led his new team to the summit of the Premier League, with the Gunner's unbeaten since his arrival at the Emirates.
Ozil netted his first goal for the club in his side's 2-0 win against Napoli in the Champions League last week, but could not save them from dropping points at the Hawthorns, drawing 1-1.
Despite the promising form of the Gunner's, Ozil still believes the best is yet to come from his new side.
Quoted on ESPN, Ozil said: "I am delighted we top the table. But we also know that the season is still very long. To talk about winning the league would be too early. The current table is nothing more than a snapshot.
"We will continue to play every game with our full concentration, we will try to get better as a team. If we can do that, we have a great chance to achieve a lot. I will give it my all."
Ozil, who is a product of the Schalke 04 youth academy, has plied his trade in three of the best leagues around after spell's in the Bundesliga, La Liga and now the Premier League.
The midfielder insists every match is a challenge in the Premier League and has been blown away by the support of the fans.
"Every match is a challenge and the games are very intense," said the German. "I believe, I can profit from that. The atmosphere in the stadium is also striking, the support of the fans, also of the away fans, is impressive."
