Marcelo shot smacks youngster in face distracted by phone during Real Madrid friendly

A lesson, if it were needed, on why you should keep your eyes on the action

Prince and some fellow musicians have tried to ban mobile phones from concerts and this footage from Real Madrid's match on Sunday suggests a ban should be considered at football stadiums too.

During Real Madrid's latest pre-season friendly, a 0-0 contest in Oslo with Norwegian side Valerenga, Marcelo took a vicious shot at goal.

But rather than stinging the palms of the goalkeeper or ripping into the back of the net, the strike from the Brazilian full-back ended up smashing a young fan in the face.

Whilst sympathy is usually extended to those struck by flying footballs, the fan only had himself to blame.

With the ball heading in his direction, the boy had his focus on his lime-green mobile phone and he thus failed to take evasive action. The result looked painful.

So there you go, think twice before checking social media and your messages next time you're at the football.
