Robson’s side were disappointing at Pittodrie on Wednesday night when they lost 1-0 against Kilmarnock on their home turf.
Aberdeen are now sitting eleventh in the Scottish Premiership standings and are under real pressure to get their results and performances sorted out in the coming weeks.
Miller stressed that Robson now must prepare himself for an avalanche of criticism as the fans were not at all happy by the end of the game against Kilmarnock and will demand explanations for the poor form.
