Manchester United have had scouts at Tottenham Hotspur's last four games to watch three of their players, according to reports.
The People claims that the main subject of United's interest is Danny Rose, who has been identified as a potential replacement for Luke Shaw as he continues his long recovery from the broken leg that he suffered in September.
However, the report adds that the Red Devils were informed by their North London counterparts that the defender was not for sale at any price.
Meanwhile, The Star On Sunday suggests that Tottenham's England internationals Harry Kane and Dele Alli are both on United's radar.
It is believed that United have been preparing dossiers on the duo, with a view to making summer bids.
