The England international was in outstanding form to keep the champions at bay, and has admitted that he was confident he would not be beaten.
"I probably haven't been under that much pressure before," he told his club's official website.
"They were attacking and we were defending, it was as simple as that. We just managed to keep them out.
"I actually had that kind of feeling where I didn't think anyone was going to beat me.
"I felt that anytime they were going to whip the ball into the box I was going either going to come and punch it or claim it or they're going to have a header and I'd save it. I really couldn't see them scoring."
