Bologna coach Sinisa Mihajlovic admits selling Marko Arnautovic to Manchester United would be a major blow.
United are expected to try again after having a €9m offer turned down on the weekend.
Mihajlovic said: "If he were to go away it would be a great loss.
"I would be happy for him , but I think he will stay in the end."
The coach added: "We talked to each other, surely if he stays here he will train well and do what he has to do. If he goes away we will see, but I don't think so."
