#4 Danny Rose
Danny Rose has been out of favour for Tottenham this season, with head coach Mauricio Pochettino preferring Ben Davies in the left back spot.
Rose did not endear himself to Spurs fans last summer when he criticised the clubs transfer policy and has since only made 7 starts for the north London club.
The Manchester United left back spot has been a problematic area for Mourinho with Ashley Young playing a make-shift role there for the majority of the season and Luke Shaw unfancied by the Portuguese. Although Young has done a good job a left back, he will turn 33 this summer and the united manager will want a longer term replacement.
Rose would add pace, a threat from deep, good crossing ability and ball retention to the red devils, his Premier League experience would also make him a good investment for United.
