Van Persie said: "I am 100 per cent convinced we will soon win big trophies. When that happens, I know the whole world will be behind us. It will be a lasting memory if we win it with our style of play.
"We started great, but at the last hurdle we did not make it. We were very unlucky. Against Liverpool in the Champions League, we were more or less in the semi-final six minutes from the end. We get one unfair penalty against us and we are out of the Champions League.
"Should we put all our philosophy and vision on the way Arsenal play overboard because of one lousy penalty? I don't think so."
