Park scored the winner against rivals Liverpool on Sunday.
“It was a great feeling to score against Liverpool,” he said.
“Derby matches are very important games, so to score the winner in one is a fantastic feeling. Doing it in front of the Stretford End was unbelievable.
“I want to score more goals for United and it doesn’t matter who they are against.
“I know I should score more goals. I feel good scoring against the big teams like Arsenal, Milan and Liverpool, but I want that experience more often.”
