Atalanta boss Stefano Colantuono wants striker Marko Livaja to calm down if he's to reach his potential.
The young forward, who is also co-owned by Inter, was criticised from all sides last season after he was accused of punching teammate Ivan Radovanovic in a training ground bust-up.
And his Coach has admitted that a bad attitude could cost his career deeply.
“If Marko can change his character then he'll become a great forward,” he told Video Bergamo.
“He has the quality to do so.
“However, if he does not put the effort into improving his temperament, then that's going to affect his growth as a player.”
