Pilkington hit a post and also missed an easy chance to put Norwich ahead when clean through against the champions, but he was on much better form Saturday, scoring twice to send Swansea City home to a despondent Wales with nothing.
"I've seen the chance I missed at United a few times. It was painful watching it," Pilkington said. "But everyone misses chances. Everyone is human. It's how you bounce back from that. The gaffer said just keep doing your stuff and the goals will come and luckily they have.
"I have been grateful that I had the chance to put it right after 48 seconds. I wasn't going to miss that one."
