The midfielder, who is on a contract worth £350,000 per week at the Emirates Stadium, has been frozen out by manager Unai Emery and has made just two appearances this season.
"If we don't do well in a big game, it's always my fault. If that's true, how do you explain our results in the big games when I wasn't involved? There's no real difference," he told The Athletic.
"I know people expect me to offer more, dictate play and make the difference — I do, too — but it's not that straightforward.
"I'm not the only player in the team and, don't forget, some of our opponents are simply better than us."
Ozil's current deal does not expire for another two years and despite his lack of game time he has insisted that he will see out his contract.
"I have a contract until the summer of 2021 and I will be staying until then," he said.
"You can go through difficult times, like this, but that is no reason to run away and I'm not going to. I'm here until at least 2021."
