Chelsea were warned. Brentford's Kevin Schade picked up the ball on 88 minutes and threw it into the Blues penalty area. The defenders let it bounce - and Robert Sanchez had to tip the ball over the bar.

It was Brentford's seventh goal from a long throw since the start of last season. No other top-flight side has more than two. A few days later the Bees got another when Aaron Hickey volleyed home from another long throw routine in the Carabao Cup win over Aston Villa. This is not just a weapon, it's a machine.
