World Cup 2010 Predictions: Wayne Rooney's Anger Could Cost England

Wayne Rooney has been warned about his bad temper on the pitch. He could cost England the World Cup if he over does it and gets sent off.   

In England's latest and last game before the start of the World Cup, they played against a South African Premier League team. Rooney scored their last goal in a 3-nil win.

However, it wasn't all plain sailing for the supreme striker. Referee Jeff Selogilwe slammed Rooney's behaviour as unacceptable.

Selogilwe booked Wayne in their game against the Platinum Stars and said:

"Rooney insulted me, he said 'F*** you'."

"He must learn to control his temper. He could get sent off in the World Cup, especially if he uses this kind of language."

"If he insults a referee like me, then he will use that vulgar language to other referees as well."

"Maybe the England players thought 'This is just a friendly, we can do what we like and the referees are not that professional."

"It's a shame. 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. So I was very disappointed in Rooney because he is my favourite player."

Rooney is known to be an animated player on the pitch, but it just shows how much he cares about England.

Critics are bringing back the memories of the World Cup 2006. The United star was red-carded in the quarter-final against Portugal. He stamped on - for stamping on Ricardo Carvalho's 'bits'.

He will need to sort out his anger issues, as a ref at the finals may be more harsh and punish him sooner rather than later.

However, his raciness is part of his playing style. Less anger may mean less passion.

Selogilwe did then say that Rooney calmed down and payed him back for the outbursts during the game:

"Actually he is still my favourite player. He apologised to me and gave me the shirt he was wearing."
