Manchester United are in contact with Borussia Dortmund for experienced defender Sokratis Papastathopoulos.
Kicker says Papastathopoulos, whose contract expires in 2019, is interesting United as well as Juventus.
The Greek defender could be looking for one more move rather than sign a new deal which is on the table at his current club.
And United boss Jose Mourinho would rather sign him this summer than wait until 2019.
Papastathopoulos is also interesting Arsenal, where former BVB chief scout Sven Mislintat now pulls the strings.
