That;s not always true. There was some demonstrable shit refereeing in that game. especially the call that led to the US penalty kick. In all my years of watching football I've never seen that call given. You're right, what Sinclair and Tancredi said to the ref was uncalled for, but I don't fault them one bit.
The refs called for it the moment they decided to make such idiotic calls. If you don't want criticism then don't do something that so obviously demands criticism.
