I start to worry that Barella is a bit limited player.
One would say he has everything in abilities to cover regista position, but his thinking is one dimensional. He went for tackles in front of defense leaving huge gap behind him... unacceptable.
Many were pointing out to Gagliardini, but Gagliardini did nothing wrong. Barella did. He didn't adapt to his role today. Our defense was shaky thanks to him. If we have not conceded 2 goals that early, we would have conceded later.
He is still a great player, but a little bit overrated (like I've read he is the best CM in Serie A)
