Manchester United are believed to be keeping tabs on Red Bull Salzburg defender Martin Hinteregger.
Reports suggest that Red Devils boss David Moyes has sent scouts to monitor the 21-year-old, who scored a goal from 70 yards in a friendly against Schalke 04 this summer.
According to talkSPORT, the centre-back, who has a contract until 2017, would command a fee of around £6m.
The Austrian Under-21 was called up to Marcel Koller's senior side for their matches against Romania and Ukraine last year, but did not feature in either.
