AC Milan director Massimiliano Mirabelli has called on Vincenzo Montella to find the team's shape.
Mirabelli was speaking before their stalemate with AEK.
“It is Montella who needs to design the team shape," Mirabelli told Sky Sport Italia.
“We knew this was not going to be easy and that this is not a positive moment for us. We are also aware that we have a great squad with strong young players.
“We must find this shape of the team so that we don't lose ground."
