There are already reminders in Alvaro Morata of the player Chelsea were looking for when they signed Fernando Torres six years ago.
The goals, of course — six from six after Saturday's hat-trick. The pace, the intuitive sense of the best positions to take up and the sheer physical strength.
Morata made his markers uncomfortable on and off the ball in the game which will teach Diego Costa what being quickly forgotten looks like, should he catch the highlights.
But beware drawing football conclusions before the leaves are on the ground.
