This game was only 20 seconds old by the time Declan Rice had left his first and second mark on Arsenal.
Straight from kick-off the midfielder snapped into the back of Gabriel Jesus. Moments later, he had pressed Thomas Partey into uncomfortable territory.
Ninety minutes later, after his energy and bite and intelligence had helped drag West Ham back from the brink, Rice was at it again. He won the ball in midfield and set up a final siege. It came to nothing but his imprint had long been seared on to the afternoon.
