The midfielder has urged the Gunners hierarchy to invest heavily this summer in a bid to close the gap on their rivals.
Cazorla told Sport 360: "Arsenal has everything to win," he adds. "History, infrastructure, an incredible stadium and great players. But we have to improve at crucial moments and sign the best football players because if you don't do that, you may lag behind others.
"That is what makes it different at other clubs. You've a good example in Manchester City who signed Fernandinho, [Alvaro] Negredo... or even Manchester United with [Robin] Van Persie and [Juan] Mata.
"Arsenal know what they need next season, but it's almost impossible to win a title if we haven't got these kind of things."
