Former AC Milan coach Fabio Capello has warned Rafael Leao over new contract talks.
Leao has talked up a move to Arsenal this week, but Capello says Leao owes his career to Milan.
He said, "If he has become what he has become, he owes it to Milan, and owes him a little gratitude which (Gigio) Donnarumma has not done.
"If there is no more gratitude, nothing can be said.
"The player has proven to be important. He too played with the handbrake a little pulled but as he freed himself he showed all his qualities, which he has yet to express."
