Sir Alex Ferguson defended his decision to give referee Mike Dean a half-time blast of his hairdryer before Manchester United sealed a come-from-behind 4-3 win.
Ferguson first rounded on Dean, then fourth official Neil Swarbrick before finally launching into assistant referee Jake Collin over Newcastle's second, an own-goal from Jonny Evans, which he was convinced should not have been allowed to stand.
"The referee changed the linesman's mind," said Ferguson after Collin had flagged for offside against Papiss Cisse, only to get over-ruled after Evans turned home Danny Simpson's cross. "He said it was an own goal. But if you see it again, and the referee can't, the guy is in an offside position, then he pulls Evans' arm."
