Juventus captain Giorgio Chiellini insisted Everton forward Moise Kean was "completely different" to Mario Balotelli.
Kean left the Serie A champions for Everton last year, with the Premier League side paying £25million (€27.5m) for the Italy forward.
The 20-year-old had scored just once in 26 appearances for Everton before this season was suspended due to the coronavirus pandemic, and was dropped in November reportedly for a disciplinary breach.
Kean was also condemned by Everton in April after an apparent breach of lockdown rules.
Having previously criticised Brescia forward Balotelli, Chiellini said Kean was nothing like the former Inter and Manchester City man.
"Balotelli only has the shot. There are those who now compare him with Moise Kean, a boy who appears rebellious and unmanageable, but is completely different from Mario," Chiellini wrote in Io, Giorgio.
"Of course, in Juventus youth he was punished many times, but when he played in the first team he always showed himself very respectful towards the group.
"Sometimes he does not hear the alarm and arrives late, but they are behaviours that can be changed without difficulty."
Kean came through the youth system at Juventus, where he scored eight goals in 21 games before his departure.
