To understand how seriously Carlo Ancelotti is taking the FA Cup - and what peril Everton were in - the cost of his substitutions told the story.
With Rotherham, next to bottom in the Championship, having secured parity and appearing capable of causing shock and embarrassment, Everton's manager turned around and summoned four players deep in the second half worth a combined £95million.
That Ancelotti was forced to take such measures illustrates how uncomfortable an afternoon that had appeared to be straightforward had become. Everton need one of those changes - £22million Abdoulaye Doucoure - to conjure a winning goal in extra-time to secure their progress.
