Prime Minister David Cameron believes that racism in football is showing 'worrying signs'.

Cameron has also insisted that footballers are role models to young people, and therefore should lead the way in the fight against racism.

"It is worrying some of the recent signs we have seen. Why I think this matters, not just to football but also to Government and everyone in our country, is because football and footballers are role models to young people," Cameron told Sky Sports News.

"What people see on the football pitch, they copy when they go to learn to play football themselves. I think it is important to bring people together and make sure we kick racism out of football for good."

Some Chelsea players were allegedly subject to racist taunts when leaving their team coach in Naples on Tuesday.
