70-year-old Craig Brown, who led the Scots to the UEFA EURO 1996 as well as the 1998 FIFA World Cup™, has taken his assistant Archie Knox with him to struggling Scottish Premier League side Aberdeen after both men resigned from Motherwell late Thursday.
Motherwell accused Aberdeen of a "gross discourtesy" and chairman John Boyle called for the Dons to delay the appointment until after the two teams meet at Pittodrie on 18 December.
Brown met Milne on Tuesday but soon categorically reaffirmed his allegiance to Motherwell, who also released a statement on Wednesday announcing their management team were staying.
But Brown publicly wavered later that day and admitted he would reconsider before resigning late Thursday night, when Aberdeen first made contact with the Lanarkshire club.
Brown and Knox will be officially unveiled on Monday, with caretaker bosses Neil Cooper and Neil Simpson remaining in charge for Saturday's Premier League clash against Hearts at Tynecastle.
