AC Milan hero Costacurta: Ibrahimovic could've done more this season

AC Milan hero Billy Costacurta has taken a swipe at the club's team manager Zlatan Ibrahimovic.

Club owners Redbird hired Ibrahimovic as an operating partner and senior advisor within Milan.

Ibrahimovic is expected to have a big role in the selection of a new coach and the transfer strategy ahead of the summer market.

However, Costacurta says he is a little disappointed with Ibrahimovic's impact on the club.

"He could have shown himself a little more, but we don't know everything that happens inside the dressing room. I know he has made his voice heard a number of times," said Costacurta.
