"It's a very important three points," Rafael told MUTV. "It wasn't a great performance from us but in the last five years we haven't won here so we're very pleased.
"It's definitely the best goal I've scored for United. It was a good moment to get it because it was so quick after they scored. If we hadn't had scored them we might have got a little bit nervous so it was an important time to get the goal.
"I was so pleased [to score] for the fans," he added. "They always give me such great support and I know this is an important game for them so I'm very happy."
