Rafael Benitez has reignited his rivalry with Sir Alex Ferguson claiming the Manchester United boss avoids punishment for unduly pressurising match officials, the Daily Mail report.

The interim Chelsea manager crossed swords with Ferguson on a number of occasions during his six-year spell at Liverpool - notably attacking his old foe in 2009 press conference for his treatment of referees and their assistants.

Ferguson has been thrust into the spotlight once again this after criticising the performance of linesman Simon Beck during the 1-1 draw on Sunday, claiming he had a ‘shocking game’ after failing to flag for a penalty after Steven Caulker's trip Wayne Rooney in the second half.

And Benitez insists it is crystal clear his Old Trafford adversary is still harassing officials without being reprimanded and questioned whether the FA will discipline the 71-year-old for his behaviour on the touchline.

"Maybe now a lot of people are seeing the same things," he said.  "I will not talk too much about that because it’s obvious. It’s a question for the FA what they do about it.

"What I said at that time was what I thought and what I’m seeing now is similar. It depends on the FA. I don’t know what they will do."
