Mihajlovic has been undergoing chemotherapy for six weeks for leukaemia, keeping in constant contact with his staff and players via streaming technology.
“He spoke to us via video conference call during the week and said he wasn't 100 per cent. He told us a month ago that he wanted to be here for this game, but we didn't think he really would be!" Orsolini told Sky Sport Italia.
“We were so happy that he made us this surprise and saw it as an extra boost. We're just sorry that we didn't give him the victory.
“I have a special rapport with the Coach, he put so much faith in me and made me feel like an important player for this team. We miss him in the locker room, obviously he's a big presence."
The midfielder added: “He's lost a bit of weight, but the grit, determination and passion were the same as always!"
