Posted by Stefano Pioli, the manager of AC Milan, stated that Samuel Chukwueze's absence was a factor in the team's Saturday night loss to Udinese.
The Zebras defeated the Rosseneri 1-0 at home in an unsatisfactory match.
The game-winning goal came from Roberto Pereyra in the 62nd minute.
Milan has now lost all four of their games in all competitions.
While on international duty last month, Chukwueze suffered a slight hamstring injury, and he hasn't played since.
Pioli acknowledged that the Nigerian winger's contribution to his team's victory at home would have been crucial.
“I'm confident that I possess valuable attributes at my disposal. Since Pulisic and Chukwueze were not available today, I made a different decision; otherwise, we know how we want to approach and attack the games.
“This was not the performance we wanted, so it is only fair that the fans jeer, especially at me. We need to do much better.”
