England striker Wayne Rooney has been told to cool it after a fiery display in the 3-0 World Cup warm-up win over South African club side Platinum Stars.
Rooney came on as a half-time substitute for Fabio Capello's side, but was booked after his introduction and told by referee Jeff Selogilwe to calm down.
Selogilwe later told the media: "I was very disappointed in Rooney because he is my favourite player. He insulted me.
"He is a good player when you see him on the TV, but when you see him on the pitch, he just keeps on insulting the referees.
"To me it looks like Rooney insults people and fouls other players. If he insults a referee like me, then he will use that vulgar language to other referees as well.
"He must learn to control his temper. He could get sent off in the World Cup, especially if he uses this kind of language."
