Manchester United boss Sir Alex Ferguson has reacted strongly to Liverpool manager Rafa Benitez's astonishing verbal assault on him last week.
Benitez blasted the Scotsman for his behaviour towards match officials, as well as berating Ferguson for complaining constantly at the fixture list which United have been handed.
However, master of mind games Ferguson played it cool after seeing his side sweep aside title rivals Chelsea 3-0 at Old Trafford.
He said: "There was a lot of venom in what he has said. I don't understand where it has come from.
"He is obviously disturbed about something. When he reflects on it he must realise what a ridiculous thing he is saying.
"But I don't want to say anything else, because all I want to do is keep my focus on my team."
Ferguson went on to admit that January is a tough month for his side, who appear to be hitting top form at just the right time.
He added: "We've got some tough games coming up now. We've got players who are playing fantastically well at the moment.
"We've got Wigan, who are playing fantastically well at the moment, on Wednesday and then Bolton away which is also a tough game.
"So there's a lot of interesting games to see in the next few weeks.
"January, as I've said, is a big month for us, I think we've got eight games in January, so it's a big test for us."
