Manchester United are eyeing Borussia Dortmund defender Neven Subotic.
The Daily Express says United are seeking alternatives after Subotic's teammate Mats Hummels rejected talk of leaving BVB this week.
United will instead turn their attentions to Subotic, who is a name that has cropped up in the past for them.
United also have Aston Villa's Ron Vlaar on their wish list, although they are thought to be readying a fresh deal to keep him at Villa Park.
It remains to be seen whether United will strengthen their defence in January.
