Marseille midfielder Joey Barton has criticised the Football Association for their decision to hand a four-match ban to John Terry for racially abusing his former QPR team-mate Anton Ferdinand.
Barton, 30, believes the Chelsea captain should have been given a longer suspension following his own 12-match ban for violent conduct.
Ex-England skipper Terry was banned and fined £220,000 by an FA independent regulatory commission for racially abusing Ferdinand during Chelsea's Premier League match at Loftus Road last season.
Terry is considering an appeal against the sanction which was delivered on Thursday after a four-day hearing at Wembley.
But Barton, who was suspended for his red card and subsequent violent conduct on the final day of last season at Manchester City, has vented his anger at the decision on Twitter.
He said: "Well I think that proves a lot. What an absolute farce. Twelve games for violent conduct and only four for that. FA should be embarrassed. Shambles.
"I was expecting at least a public execution after a year.
"Twelve games!!! By the FA's perverse reckoning, I'd have got less of a ban for racially abusing the Man City players than tickling them as I did. In what circumstance can that be right?"
MP Damian Collins, a member of the culture, media and sport committee that produced a report on racism in football earlier this month, said Terry should now admit what he did was wrong.
"It would be good if there was some sort of recognition on John Terry's part that what he did was wrong," said Collins. "This is something football should learn from."
Collins added the FA must establish a consistent scale of penalties after Liverpool's Luis Suarez was given an eight-match suspension for racially abusing Manchester United's Patrice Evra earlier this year.(reopens) Kick it Out's Lord Herman Ouseley told BBC Radio 5 Live: "This is not about recriminations. It's about how football moves forward from here after it has spent 11 months going through the wringer.
"People are trying to make the game a better place to be. Seven million people play on a regular basis and we want them to play in an atmosphere of no abuse."
