The Norwich winger headed home the only goal of the game at Carrow Road and was ecstatic after missing several chances in a defeat to the Red Devils at Old Trafford last season
The former United trainee missed two gilt-edged chances as the Norfolk side fell to defeat at Old Trafford last season, and believes he can now put those worries to rest.
“It's good to put those demons away,” Pilkington told reporters. “I could have scored a couple at Old Trafford [last season] but I think I've redeemed myself tonight.
“We're keeping clean sheets against massive teams. It's great to be here at the moment.
“You can't beat playing in the Premier League. Last year we didn't get any big wins and this year we have three already [against Arsenal, Tottenham and Manchester United].
“We always knew we could pick up points and that's what we're starting to do.”
Pilkington admitted that the win over the Red Devils was significant for the Canaries, as they continue to recover from a poor start to the season.
“Whenever you play against Man United, no matter who you are, you're always going to feel up for it,” he continued.
“It's three points at the end of the day just like it's three against any other team. But it's one for the fans to enjoy.
“We had a few games where we had a shaky performance but today we showed everyone what we can do.
“We always knew we could win games in this league just like we did last season. The boys just needed to start believing in themselves to start beating teams like this and that's what we've done, and now we're unbeaten in six.”
Wes Hoolahan was also impressive in midfield and hailed the home support for inspiring the players to victory.
"It's amazing,” he told ESPN. “It's a great result and credit to the fans, they roared us on and we were due a win against one of the big teams.
"The team was excellent today, we worked hard and a great goal by Pilkington there at the end."
