'Emotional' Mourinho should apologise - McCarthy

On Thursday, Chelsea head coach Liam Rosenior said there must be a zero-tolerance policy applied to anyone found guilty of racist behaviour in football.

He said: "If any player, any coach or any manager is found guilty of racism, they shouldn't be in the game. It's as simple as that."

The former Hull City boss added that the problems were not confined to football and that racism is a problem across society.

"A lot of things (need to change), this is a very complex situation when you speak about race or gender. There are a lot of things that need to change in society," said Rosenior.

"It sickens me to be honest. I think there's a wider debate than football. I think there needs to be more accountability for these things that need to be stamped out.

McCarthy agrees that the problem of racism extends far beyond football.

"In society today, people aren't open to talking about it. We still don't have these conversations," he said.

"There's one race that wants to have this conversation and the other race isn't ready. In anger, you can come out with a phrase like that but you're quick to say I'm not a racist.

"Yet you use the underlying racist thing when you're angry. For this problem to go away, both parties and both races have to be willing to talk about these things."
