PFA chairman Clark Carlisle says Chelsea skipper John Terry's four-match ban wasn't enough.

Carlisle insists a four-match ban for using abusing Anton Ferdinand is too lenient and undermines the work against racism.

He said: "The Luis Suarez eight-match ban really sent out a strong message to the members of the union and the public that racism isn't tolerated in the game. To dilute that with this four-match ban has almost undermined the initial message."

He said players banned in racism cases should take part in anti-discrimination lessons.

He added: "It shows that they do show some remorse for their actions with a willingness to contribute to the campaigns so that other people are aware of the message that's being sent.

"If (Terry) doesn't contest this decision and an appeal isn't forthcoming it would do John Terry's image a lot of good if he was seen to be contributing to these sort of campaigns."
