Chelsea boss Jose Mourinho risks further FA action after criticising Robin van Persie elbow

Chelsea manager Jose Mourinho could be in hot water with the Football Association again after slamming the governing body for double standards over Manchester United striker Robin van Persie's elbow on James Tomkins.

Van Persie went unpunished for the incident in United's match against West Ham United despite it being in full view of referee Mark Clattenburg, who spoke at length with the player before play continued, while Tomkins claims the elbow was malicious.

The FA is unable to take retrospective action against Van Persie as the incident was in full view of the referee and Mourinho has gone on the attack for double standards, after Chelsea midfielder Ramires was banned for four matches for striking Sebastian Larsson last season.

"The same people that suspended my player [Costa] didn't want to suspend a player this weekend," Mourinho said. "A player did this in the face of somebody else and nothing happened.

"I know that if it was one of mine, I know. Last season the same thing happened, when Ramires was suspended.

"It was exactly the same thing. And one week later, a Manchester City player [Yaya Toure] kicked a player on the floor at Norwich [Ricky van Wolfswinkel] and nothing happened. I'm used to it."

Ramires was banned retrospectively by the FA after the off-the-ball incident, which was not in view of the official Mike Dean in the defeat to Sunderland last April, all but ended Chelsea's Premier League title challenge.

After being found guilty of misconduct, fined £25,000 and warned regarding his future conduct in January, Mourinho is already walking the disciplinary tightrope and could face further action from the FA should it deem his comments breach its regulations.

Mourinho could yet face action from the Premier League after skipping his pre-match media duties prior to the clash with Manchester City in January, amid a campaign that has been bathed in off-the-field controversies.
