A heat map vaguely shows average positions over 90 minutes. It does not show the attacking or defensive phases. It doesn't show where the opposition are. The average is very misleading.
I'm talking about the relative positions of the 2 deepest midfielders during the game, it is clearly clear that Dier is the deeper and more defensive.
When Dier and Mason have played together it was definitely one go, one stay - they alternated. Alli maybe gets back a bit less, but by-and-large all our CM combinations do double pivot defending
