The Gunners currently sit two points clear of Liverpool at the summit, with Ozil playing a key role for Arsene Wenger's since arriving from Real Madrid for £40 million on transfer deadline day.
And Cazorla says that the German's ability to turn a match on its head has been a "gift".
"He brings us something different, because he’s all talent, what he does is magic," he told El Pais. "It seems like he’s not there and then he changes a game with one control, one pass.
"It surprised us that he came to Arsenal, because you don’t expect him to leave Madrid and then choose our team. For us he’s a gift."
The Spaniard also believes the team as a whole have improved upon last season, having cut out mistakes and therefore improved their consistency.
"We had to be more consistent and we are now, that is a defect that we have corrected. The team is not as ‘innocent’, we are committing fewer errors.
"Last year, through forgetfulness or lack of concentration, we lost games stupidly and we have learned from that."
Although Ozil's arrival has contributed to Cazorla being pushed out to the left-hand side, he says he has been given increased freedom by Wenger.
"The football is England is less tactical, it’s more open. It has given me absolute freedom. Although I play out a little on the left, he lets me go into the centre, to change positions, and I like that a lot," he said.
Cazorla also hailed the competitive nature of the English game, and believes Liverpool can go all the way this season.
"The Premier League is very open," he continued. "[Manchester] United beat us and they are now only five points behind, just like that things can change. And then there is Liverpool, who are the surprise of the campaign and I think are serious candidates because they have strengthened well.
"They have put together a compact team and they have the advantage of only playing in one competition [rather than in Europe]. But look at [Manchester] City, who lost against Sunderland, or Tottenham, who lost at home. The Premier League is not easy, it’s not Spain, it’s more equal."
