Sir Alex Ferguson has rejected Rafael Benitez's accusations that he refused to shake hands with the Chelsea manager ahead of last Sunday's FA Cup tie at Old Trafford.
Benitez claimed he was waiting to shake hands with the Manchester United boss before the game but Ferguson walked past him without doing so.
The Chelsea interim manager said: "I was waiting at the beginning. It's up to him, I was in the way waiting."
Asked why Ferguson might have done so, Benitez added: "Ask him - if you are brave enough ask him. It was his decision. I was ready and waiting. I have some education because I know a lot of people are watching so I know what I have to do."
But speaking on Friday at his press conference ahead of Saturday's Premier League clash with Reading , Ferguson said: "It is nonsense. Why would I refuse to shake his hand?
"I was signing autographs and I never saw him. Why he has said that I have no idea. If he wanted to shake hands he could have stood straight in front of me.
