Liverpool boss Jurgen Klopp was upset with a fan who invaded the pitch and slid into Andy Robertson during a goal celebration.

The Reds enjoyed one of the most famous wins in their Premier League era, defeating Manchester United 7-0 at Anfield on Sunday.

During one of the goals, a pitch invader raced onto the field and nearly injured Roberston during the celebrations.

Klopp was seen on television furiously reacting to the incident.

The German was shouting in the direction of the fan, as he was being taken away by stadium officials.

Robertson did not appear to suffer any serious injury as a result of the incident.
