The defender feels the Bianconeri will fall short domestically and in Europe if they fail to address their current problems at the back
Giorgio Chiellini has stressed that Juventus must improve in defence if they are to be successful this season.
The Italian champions kept their second clean sheet of the Serie A season in this weekend's 1-0 victory over rivals Torino, but Chiellini feels they still have plenty of room for improvement at the back.
"We have to improve in certain aspects," the 29-year-old told Corriere dello Sport.
"We’ve conceded a few goals this season due to a lack of focus, even if we have managed to win almost all of our games.
"Saying that, against Torino, we ran no risks at all at the back."
