3. Sebastian Jung
A bit of a long shot really but someone who could be hugely beneficial for Manchester United in the future as well. Jung might be only 24-years-old and a bit of an unknown quantity but in the Bundesliga he is one of the rising talents in a brilliant Wolfsburg team. Capable of attacking as well as defending really well, Jung even got a chance to play for the German national senior squad and made an appearance for them. He still needs to hone his game if he is to be considered as one of the best right backs in the world and where else could he learn more than under the tutelage of Louis Van Gaal? Jung would be a young and cheap alternative to some of the bigger names out there but a risk in terms of moving to a new country and to a new league at such a youngish age.
