Roy Keane has labelled Chelsea boss Jose Mourinho a "disgrace" following his antics during the Blues' 3-0 win over Aston Villa.
The Portuguese went to shake the hands of Villa boss Paul Lambert and Keane before the end of his side's victory at Stamford Bridge last month.
Mourinho's actions left the Villa assistant boss unimpressed, and he feels that the 51-year-old would have been punched for his behaviour in Sunday league football.
When asked why he didn't shake Mourinho's hand, Keane told reporters: "Because the game is still going on.
"I don't mind all that but the game is still going on. It's disgraceful, I've seen him doing it to other managers, it's a disgrace.
"The game is still going on. You wouldn't do that on a Sunday morning, you would get knocked out."
Keane also admitted, ahead of the release of his autobiography, that he was unsure whether he could forgive Sir Alex Ferguson for remarks made about him last year.
