I don't usually watch other teams. Not regularly at least. But what I saw yesterday was inexcusable. Just out of the top of my head, we had 5-6 clear chances we didn't convert. Two clear shots on goal by Marchisio both on the keeper. Two clean headers in front of goal wasted by Llorente and Moratta's post. With any serious team, we would have been punished.
Also, remember with Olympiacos. We wasted a lot of chances once more. Last year with the Scandinavians as well.
This can't continue when you are playing at the top level. Efficiency should be a given. I am glad that Allegri was angry about this. It said a lot about the guy in my eyes.
