Lewis Cook, years off parenthood, took the message to heart.
He was the heartbeat of the team as it dominated the second period, never far from the ball and always on the end of it when crosses came into the box.
It feels like a point that has been repeated throughout this campaign, but if Cook is on form so are Leeds.
He is only 18, which is a caveat with which any questions over displays have to be regarded.
Given a year or two, there is a potentially brilliant player in the academy graduate.
It is now to be seen whether that will be at Leeds.
