Crotone were completely packed and didn't form much pressure on our left side. Obviously Nagatomo's going to be comfortable while zooming around in their area. There were multiple times where he didn't connect with Perisic who wasn't happy about it (e.g. should've made an obvious simple pass to Perisic instead of making a wasteful cross). He's still a complete push-over and a liability when facing an actual threat/pressure. He has to be replaced as soon as January before we regret it in a decisive game.
While saying that, Dalbert was very disappointing against Crotone specially when going forward. His crosses were worse than Candreva's. D'Ambrosio has been our best and most reliable fullback so far.
