Two wrongfully denied dos Santos goals brought unwanted attention to the World Cup referees, and made them targets of many trolls and memes across Twitter

Friday saw what should have been an exciting World Cup fixture between the rising stars of the Mexican national team and the always entertaining Samuel Eto'o and his Cameroon side.

The game, though, proved nothing but that as it ended in disappointing fashion.

Despite the slim 1-0 scoreline in favor of Herrera's men, El Tri dominated much of the game with the Indomitable Lions putting up very little attacking threat.

But what the game did do was cast doubt over the ability of FIFA's referees to officiate games to the highest standard. 

The most talked about topic of the match had nothing to do with the performance of the players but rather the linesman, who had controversially ruled out two goals by Villarreal striker Giovani dos Santos as offside though the replay showed the goals should have stood as the the Mexican was onside for both.

And this was the second 

This, as expected, led to many hilarious trolls and memes to blow up all over Twitter as the world took notice of what had been another shocking performance from the World Cup officials.
