Seven inches, that's what separates Sammy Ameobi and Connor Roberts.
Ameobi comes out on the taller side at six feet four inches. Roberts comes in at a more modest five feet nine. There are no excuses for Ameobi losing a header in this match-up. None.
And yet he did, quite convincingly, inside his own box on the stroke of half-time. Maybe his mind had wandered off to the interval. Maybe he underestimated Roberts. Maybe it was a total absence of thinking that did it.
Andre Ayew recycled an attack by hooking the ball back into the Forest area more in hope than anything else.
