Zero positional and tactical awareness .. a mess
Based on one mistake? We know how mess looks, he makes 10 mistakes per game (Calabria)
Duarte was not as bad as people making him out to be. I think he is better than Mussachio. I bet it's like hell to try to stamp your name in the starting lineup knowing you're flanked by Calabria.
The immobile goal was not an error, he was beaten by good attacking movement (running from the blind side). The second goal he could have done better by heading the ball sideways, but also the fault was that Pioli didn't realize that the midfield was on low gas and needed a player there to pick up the second ball.
