Manchester United have 'bid £45million' for Fiorentina central defender Nikola Milenkovic. 

Ole Gunnar Solskjaer wants to bring in Harry Maguire for £75m but is looking at back-up options in case that deal cannot be made. 

City are also interested in Maguire so the move for Milenkovic, according to reports in Italy via the Mirror, is as a secondary option.
