"We believe in ourselves. If you see the games against the big clubs, we won against them so we know our quality, if we play our game we can win the league," Ozil told reporters after the game.
"We will give our best all the season for the title. We have had a lot of difficult games, we are happy to win against Manchester City and we take the three points.
"I'm happy to help the team. You see on the pitch that my team mates help me to play my game. I just help them in return so today was another important game for us.

"I tried to give my best and we won the game, so we take the three points and that's the most important thing."
Theo Walcott believes Ozil's red-hot form is making life easier for Arsenal as the Germany international leads the Gunners' assault on the title.
The World Cup winner set up Walcott and Olivier Giroud on Monday to register his 14th and 15th assists of the season and is on course to beat Thierry Henry's record for the most assists in a single campaign (20), which the Frenchman set 13 years ago.
"The thing about Mesut is that he sees things that most players don't even see on the pitch. You just have to make that run," Walcott said.
"We've got special players on the pitch who provide special moments in the match, and that makes our jobs so much easier.
"The amount he gives to this team, the threat going forward and also defensively, he puts a shift in and people don't see that side of the game which has changed in the whole squad."
Arsenal travel to take on 12th-placed Southampton in the league on Saturday.
