Crazy penalty missing for Mandzukic vs Udinese

As you can see from the video below, it appears as though Mandzukic should have won a penalty from Udinese defender Ali Adnan, who then proceeded to antagonise the Croatian and both men are issued a yellow card.
However, three seconds later after saying something to the referee, Mandzukic gets his marching orders with a second yellow card. Unbelievable scenes!
Whether Juve can hang on remains to be seen, but ahead of the game, Allegri had already said he was fully prepared to win ugly on this occasion, as long as they do actually win.
