PFA chief Gordon Taylor supports the FA's eight-match ban for Liverpool striker Luis Suarez.
Taylor says the FA must have had 'compelling evidence' to reach such a decision and feels it is important that players know for the future that racist behaviour will be punished.
"We are a multicultural society but also our football is very cosmopolitan and it is important that we send out the strongest message if there has been racist abuse," Taylor told Sky Sports News.
"Clearly it is an Independent Regulatory Commission set up by the FA. They must have had compelling evidence to come out with such a very strong sanction as a deterrent for the future."
