5. Marco Reus
Van Gaal is known to love having wingers in his side and Reus is one of the best in the world. Quick, powerful and skillful, he is probably Dortmund’s best player.
That means the German club are highly unlikely to part with the 25-year-old. Jurgen Klopp has already spoken of his desire to see Reus remain at the Signal Iduna Park for many years.
Unfortunately for Dortmund, Reus is yet to sign a new deal. There is a clause in his current contract that says he can leave next summer if a club bids £27.6 million.
The German is certainly worth more than that so the Bundesliga giants may decide to cash in on him if a club like United make a huge offer in January.
