How dare we expect to knock out a 10man Porto!
He put all we have in the game, what else should he do?
These is his first freaking season as a coach, without pre season, playing 3 times a week, with most of the players injured...
He was not ready? yes Probably! but then blame the person who gave him the job! not him.
There are not excuses for the lost, but surely Pirlo is NOT THE PROBLEM and if you thing he is, you are missing the last 4 years of bad decisions in these team.
