The 28-year-old, who is available on a free transfer this summer, made a host of notable saves as Mexico held the World Cup hosts in their Group A clash.
"Yes, there's no doubt about that. To play like that during a World Cup against the hosts and keep a clean sheet... that's not easy," he told reporters.
"I thank God that it all turned out like it did. I'm very happy, I never gave up and I kept plugging away. Now I just want to enjoy the moment with my teammates and my family, who are suffering like I am."
Both Mexico and Brazil have collected four points from their first two group games.
