The Guardian says Ferguson has brought an end to diplomatic relations with the press and promised that it will remain that way until he leaves Manchester United.
"You will never get any help out of me again," he said, expletives removed, addressing football writers who had flown to Denmark with his team for tonight's Champions League game against Aalborg.
Ferguson was addressing a grudge he had stored up since United's pre-season trip to South Africa, when he gave an interview in which he highlighted the number of players at Chelsea who were aged 30 and above and questioned how much improvement could be expected of a team that age. He was angry when this was reported in several newspapers as him talking of Chelsea as an "old team".
"I gave you access in South Africa and I shouldn't have given you access," he said. "It won't happen again. From now on, no matter how many miles you travel to get an interview, you won't get one."
Ferguson was compelled to attend Uefa's mandatory pre-match press conference, and would have been fined had he not appeared.
