AC Milan chief Massimiliano Mirabelli has no doubts about the potential of Andre Silva.

The Portugal striker has struggled in his first season in Serie A.

But Mirabelli told RMC: "Silva is not giving what we expected, we are sure to have a footballer who will in the future be among the world's best forwards.

"Little by little, during the season, you are learning about new purchases, we criticized at the beginning (Hakan) Calhanoglu, now he is showing his potential, Silva seems to be behind everyone, but we are convinced that we have a great player on our hands."
