It's the typical situation with international football and fans who pretend they care about their national team but they really don't.
Milanisti went to the stadium only to boo Donnarumma and then they bashed Mancini for not calling up Tonali.
Juventini were bashing Bastoni, Insigne and Di Lorenzo but they had no criticism for Bonucci and Bernardeschi.
Bastoni wasn't good last night but he certainly wasn't the worst player yesterday. He's at fault for the first goal (in second all the defense was disorganized) but he also saved Italy from many dangerous situations.
The main problem was his defensive partner, Bonucci, didn't give him security which made him insecure in his game. He was much better in the second half next to Chiellini.
It was also a huge mistake of Mancini to switch to a back 3 with Bastoni in the middle and Di Lorenzo and Emerson on the sides. We have seen it at Inter. Bastoni isn't suited for the role. He can only play on the left in a back 3.
