Sir Alex Ferguson has fiercely denied claims from Portugal coach Luiz Felipe Scolari that Manchester United assistant Carlos Queiroz is after his job.
Scolari made the outburst after Queiroz attended Portugal's Euro 2008 qualifying victory over Kazakhstan on Wednesday.
"The comment Scolari made about Carlos hanging about the Portugal games looking for a job was a crazy thing to say," said Ferguson.
"I am sure Scolari goes to watch Porto and Benfica at some point. Is he after the guy's job?
"I had three of my coaches and all my scouts out at games in Europe this week. I am sure they are all still working for me. "
Ferguson also slammed Scolari for claiming Queiroz and United were offering conflicting reports on an ankle injury suffered by Cristiano Ronaldo who scored one of the goals in Portugal's 3-0 victory.
"It confuses me that Scolari inferred Carlos spoke to him and marked his card that Ronaldo was all right but we were giving a different story to the press to keep Manchester United's fans happy," he continued.
"By the time I got back into the dressing room last week, Cristiano had gone to catch a plane. I didn't know what condition he was in.
"What we said was it would be up to the Portugal medical staff to do that. It was an important qualifying game for them and if Cristiano was fit, we were happy for him to play."
