How Ronaldo score from Oxford

The 2 goals were great.
I've watched a video that some guys in the court booed Cristiano.
It's really not wise and foolish to do. Why were these guys booing? Were they jealous of him.
It's sad that they neglected the talents of a footballer.
They just focused on one single event. A event that they imagined(no one knows the true. I don't neither, but I won't hate Rooney. Hating people is not wise and wastes my own precious time). Can they be more rational?
