3. Carlos Soler (Valencia)
Young midfielder Carlos Soler is really making a name for himself with Valencia this season, and according to reports in Spain, United have been scouting him for quite some time. Jose Mourinho is looking for a creative option in his midfield and the 20 year-old fits the bill. Versatile and hard-working, he could be a replacement for Ander Herrera who is out of contract in the summer. Soler is rated at around £30million, and United are willing to pay up according to the Daily Mail.
