Kagawa had a tap-in midway through the first-half of Saturday's 3-2 win.
He told the Daily Mail: "That wasn't the sort of goal I usually score so I hope next time I will show the United fans what I can do from longer range. My game is not just about scoring, though. I like to create openings. I was really disappointed to see the flag go up after I was involved in the move that led to Rafael's offside 'goal'."
