Instead, both an alleged V-sign to referee Andre Marriner in the recent defeat to Wigan and a nasty-looking challenge on Portsmouth's Michael Brown at Anfield on Monday have both gone unpunished.

It (the disciplinary panel) is a dysfunctional unit. I don't know what they are doing."
Ferguson has long held the view that his side are disadvantaged in their dealings with the FA.
The latest events will not have altered that opinion given Ferdinand had an additional match added to what would have been a three-game suspension for what was deemed to be a "frivolous" appeal over the Fagan incident.
At the time, Ferguson highlighted what he felt was a similar incident involving another Liverpool player, Javier Mascherano, at Leeds during a Carling Cup tie earlier in the campaign which, like the Gerrard situations, did not warrant any further attention.
"There is no consistency for a start and I didn't expect to get any," continued Ferguson. "I am not too bothered about it. They can do what they want down there. It is crazy at times."
Meanwhile, Ryan Giggs will return to the United squad for the clash with Liverpool.
Giggs has missed seven games since breaking his arm at Aston Villa last month but has returned to training without a problem and is expected to start against Rafael Benitez's men.
Nemanja Vidic will be hoping to stay on the pitch after being sent off the last three times he has faced Liverpool, but United need to arrest a similarly length losing run if they are to retain top spot.
