Given that Bologna are reluctant to accept a deal, Manchester United may have trouble signing Marko Arnautovic, a crucial player for the Serie A team who scored 14 goals last season.

The Bologna initiative saw the international Austrian player being brought in from Shanghai's port a year ago for €3 million, because Bologna have seen it as part of their project.

Bologna turned down a bid that was almost three times as much, and Director Marco di Vaio insists that Arnautovic is not for sale.
