Manchester United have reportedly placed Borussia Dortmund centre-back Mats Hummels as their number one defensive target this summer.
The Red Devils are in the hunt for new defenders following the departures of Nemanja Vidic and Rio Ferdinand.
Widespread reports have claimed that manager Louis van Gaal is considering a swoop for Arsenal's Thomas Vermaelen, but Hummels is believed to be at the top of the list.
Richard Tanner, who writes for The Express, told talkSPORT that while the German centre-back is United's main priority, the North-West outfit may struggle to sign him because the 25-year-old is not keen on moving to Old Trafford.
United have already signed left-back Luke Shaw from Southampton and Athletic Bilbao midfielder Ander Herrera.
