Calma. I said he had a bad game no? I'm not shifting the blame to Rugani, but it's not a secret that a CB pairing of two rather passive defenders in Rugani and Bonucci is bound to struggle on counters. Both of them work better with an agressive CB alongside them, being Benatia or Chiello. That's why BonBon and Chiello are such a good pairing for me, cause they compliment each other. Having the right partner with perfect understanding can make a huge difference.
The one on ones...Yeah, BonBon has never been good at one on ones, but over the years we've managed to minimize these situations. Rarely ever you see a striker running at our CB's uncovered like that, if it happens though, it's easy for a CB to look stupid in a situation like that. Chiello most definitely would have defended that better, but even he's been burned at one on ones before.
Btw. If we concede like that, credit also has to go to our non existing mid. Matuidi has been missed big time.
