A fan in Brazil invaded the pitch and attempted to show the goalkeeper how to save shots in some truly hilarious scenes.
Santa Cruz lost 2-1 to ASA in Serie D, the fourth tier of Brazilian football, and one of the supporters was not happy with the performance of the 'keeper.
The visitors went 1-0 up through an own goal from Alex Alves Cardoso in the first half, before Rafael Victor de Oliveira Furtado equalised for Santa Cruz in the 78th minute.
But Roger Gaucho bagged a late winner for ASA, who are top of the league.

Then, straight after the final whistle, a bucket hat and flip flop wearing fan made his way onto the pitch at the Arruda Stadium and humiliated his own goalkeeper, Klever Rodrigo Gomes Rufino.
Klever was still in his goal when the fan ended up in his vicinity, theatrically diving about right in front of him and giving him some pointers.

His saves were entirely imaginary as there was no ball to be seen and there were mass cheers from the 20,000 fans in attendance.
Klever didn't really react to the fan's antics in any way, instead just collecting his drink and towel and walking off.
A steward came onto the pitch to thwart the supporter but although he put his hat back on, started pretending he was a goalkeeper again.
Staggeringly, that led to riot police intervening and forcefully removing him from the pitch and taking him away down the tunnel with his tail between his legs.

The video of the hilarity has amassed over 1.2 million views on Twitter, giving the fan his 15 minutes of fame.
