#4 Danny Rose
The Tottenham and England left-back developed into one of the best full-backs in the country. Due to the knee injury that saw him miss out on the first couple of months of the season, Rose lost his place to Ben Davies in the Tottenham lineup and also his place in the England national team.
Luke Shaw's failure at United is forcing Mourinho to look for a replacement. Ashley Young, Daley Blind and Matteo Darmian have done a decent job but Mourinho needs a permanent left back solution.
When in form, there is no left back in the country who is as good as Danny Rose. Rose is an aggressive defender who is never afraid to go into tackles. He covers a lot of ground and is excellent at overlapping runs and can deliver beautiful crosses into the box.
Manchester United are ready to spend as much as £50million for Rose but Tottenham chairman Daniel Levy may not want to sell him to a direct rival. The possibility of a deal may finally boil down to United's determination and Rose willingness to leave his boyhood club.
