I meant to say "start him now and then" and tbh I can see why he did in this game, if the guy is training well, Allegri is one of those who will give players a chance. I know it's easy to say we start Yildiz every game but a coach always gets called out when things go wrong far more than the other way around.
It's not news to say Milik is the inferior player. He could just as easily had a couple of goals tonight in a universe where he pulls out of that and then it's no problem.
Allegri took his foot off the gas with the lineup as it looked an easier game on paper, and Milik's idiocy hung everyone out to dry. Still, I agree that at home even with 10, even for a long time, we should be doing more to win the game. But that's what an attacking coach does, quite often they lose but sometimes win. Allegri was never going to be the coach to try that.
