What he saw and whistled for was ok albeit too often, this is about what he didn't see. Batres stands far from the action, maybe he had a little problem with the height (1700 metres?) he didn't seem very eager to run with the crowd.
And he didn't see the Algerians strongarming their opponents in the box - not enough for a penalty perhaps, but more than enough for at least a warning. To tell them he had seen them doing it.
And he missed Djebbour hitting Suler in the face on purpose with his shoulder.
And Batres could have given the advantage every now and then.
I know Algeria beat the Egyptians and Slovenia beat Russia, quite a feat. But it doesn't make them good teams at all. Maybe there should be less European teams in the World Cup. Both teams did not really show a willingness to go for it.
