Uh, I said I was intelligent. Never once said that was directly related to the penalty calls so don't put words in my mouth. Dumbass.
You're clearly biased. Legrottaglie had his hands all over the guy and Zebina did the same thing. Next thing you'll say Del Grosso deserved to be sent off. He got his second yellow for practically nothing.
Really don't know why you bother.
First one almost surely not a penalty. Matri was backing in 3 times via his motion. You cant say when attackers uses his body, its being physical, when defenders retaliates in return, its penalty. That would be a clear double standard. Its was a case half dozen to the other in field, where referee gives the call depending on who started the incident initially. But nobody gives those around penalty box, because once you start calling Legro's "foul" then you end up with 6-7.
My interpretation is that referee gave that call, because he suspected David Trezeguet was in off-side position (which replays show he clearly was not). Thus referee basically, from his perspective, gave a benefit of doubt to Juve. So when Matri incidence arose, referee had to equal to scores, by not looking at the incident on its own, i.e. who started tugging and pulling, which Matri did, but in relation how he managed initially. But he soon realized he made a mistake, because there were bunch of Juve players going crazy, and that is pretty good indication that you as a ref made a mistake.
Zebina one has more meat into it, when it comes down to penalty decision. It was clearly foul. But if you call those, then, again, you have to call penalty all the time, which referee won't because they dont want match to be decided by penalites. But you cant ignore some fouls, and recognize some, hence you rarely seen those given. But in this case, at least, Zebina was sole offender, so if referee thinks the contact was above normal, then he had rights to give it. But players all knew that new Argentinian boy dived, so afterwards, not only you had mad Juve players, but Juve players diving at slightest of touches knowng referee will fall for it everytime. Sure enough, he gave red to Del Grosso, when nothing malicious happend, and free-kick involving Del Piero, if anythingelse, Ale gave Bianco defender a slight nudge on the back to win the ball, and having been dispossessed simply run into him.
Ref just had terrible for both sides, and in the end, Cagliari is a bit more unfortunate not because refereeing decisions, but the fact that Juve created nothing, and yet decisive forwards who can decide the match.
