Man United have reportedly agreed a €35m fee for Bailly in recent days but Mourinho would not be satisfied with just his capture.
The Portuguese will also look to add an experienced defender as he bids to reshape the imbalanced squad he inherited from Louis van Gaal.
However, a large part of that was down to the world-class form of David de Gea in-between the sticks.
Blind, in particular, doesn’t quite look like a natural defender and his physical profile goes against the strong, athletic mould that Mourinho has favoured over the course of his career. It is highly unlikely that Blind and Smalling will be playing together again come the first game of next season.
