AC Milan chief exec Marco Fassone admits Nikola Kalinic has struggled in his first season with the Rossonero.
Kalinic joined Milan last summer from Fiorentina.
“The attack is one of the areas we're certainly worked on," Fassone confirmed on Radio Anch'io Sport.
“We haven't scored enough goals and that's clear to everyone. I won't make any promises, but I know that when you talk about the history of Milan you talk about great strikers.
“Kalinic is a player who has always score, but he's had difficult settling, even though he's improved in recent games.
“Mario Mandzukic or Karim Benzema? There's nothing on those players."
