Schwarzer saved Mikel Arteta's spotkick in injury-time to earn a point for the Cottagers.
"They had a great chance to win the game with the last kick,” Kacaniklic told fulhamfc.com. “But Mark Schwarzer made an incredible stop to keep out Arteta's penalty. I think we could have considered ourselves extremely unlucky had Arsenal taken all three points.
"We have one of the best 'keepers around though, and that's what he is all about - making important stops. You could say that he saved the day.”
