LONDON (AP) — A referee wore a camera for the first time in an English Premier League match as Crystal Palace beat up Manchester United 4-0 on Monday.

Footage from the device worn by Jarred Gillett, dubbed the RefCam, was not broadcast live but will be wound into a program made by the league to show the ups and downs of refereeing at the highest level.

What it will also show is a closeup of United’s woeful defending.

Defenders backed off Michael Olise and allowed him to stride forward unchallenged and score the opener after 13 minutes.

Jean-Philippe Mateta made it 2-0 five minutes before halftime when he skinned Jonny Evans and hammered the ball into the roof of the net.

The United defense failed to deal with a ball into the box and Tyrick Mitchell slid in to poke home a third nearly an hour in.

The fourth came soon after when Casemiro was dispossessed by Daniel Muñoz, who cut the ball back for Olise to score his second.
