Joao Pedro waited. Brighton's Brazilian attacker had somehow evaded the attention of nine Manchester United defenders inside their own box.
All eyes were firmly fixed on Simon Adingra, who had the ball at his feet on the other side of the penalty area.
Diogo Dalot stood off and Adingra cut inside, before floating a cross to the far post.
This was now Pedro's time and the forward, still unnoticed and lurking in acres of space, powered home his header to send the Amex Stadium into delirium and condemn United to yet another damaging defeat on the road.
