AC Milan players walked off the pitch on Thursday in an Italian friendly match, after black players in the team were abused by a section of the crowd.
The Football Association in England (FA) has been talking about the problem for years - but not everyone in the game thinks enough progress has been made.
A few months ago, the Reading player Jason Roberts refused to wear a T-shirt for the anti-racism campaign "Kick It Out", saying the FA had to go further.
Speaking to the Today programme, he said: "Things are going to happen but you'd like to know that authorities are going to deal with it in the correct manner."
"People want there to be a strong message that this is totally unacceptable, and there is a true zero tolerance message.
"I think people want to believe we're past that. I wanted to believe we were past that, with the good work that Kick It Out has done.... but I think their message has become dated. A lot of things have to be looked at again."
