Mexico is playing Cameroon in their first match of the World Cup and it was a frustrating start for the Mexicans in Brazil. Giovani had two goals disallowed because of controversial offsides calls. You can see the first below, which appeared to be the wrong call.
The second, which was much closer, came when a corner was deflected just before Dos Santos was able to bury it into the back of the net.
As you can imagine, Dos Santos was not happy about his bad luck.
