Leonardo Bonucci. Obviously, Lindelöf is nowhere near the level of current Bonucci (who leads the best defense around at Juventus), and is a bit inconsistent given his age - so he has a lot of developing to do. But from a stylistic and functional perspective, he's a good match for the Italian - comfortable on the ball (not just pass accuracy stat but making them count), sees the field, good defensive mentality and leadership potential. Bear in mind that at Lindelöf's current age, Bonucci was shuttling back and forth on loan from Internazionale to Treviso and Pisa. Plus, he's also versatile like young Bonucci (who played DM and some wide defender before becoming full time sweeper/centerback). Dunno if Lindelöf if the right player for United at this moment in time especially when you consider the transition from Primeira Liga to United (ideally, we would sign an absolute defensive stalwart), but if José wants him - then you can rest assured he'll be an astute signing because Mourinho is a centerback whisperer and could really fast-track Lindelöf's growth.
