#2 Neymar (PSG)
Currently, the most expensive player in the history of football, Neymar joined PSG last summer but could be on the move again. There has been constant speculation that his move to PSG was just a part of a bigger plan of his to move to the Bernabeu, in order to win the Ballon d'Or.
With Cristiano Ronaldo at the twilight of his career, Los Blancos will need someone on the left wing and Neymar is the ideal candidate for that. His biggest asset is his skill and ability to dribble and influence games by making runs from deep.
Though many have stated that Neymar's move away from the Parc des Princes this summer is impossible, the rumors have refused to go away. Earlier, there were reports that stated Neymar was unhappy at PSG and his relationship with Cavani added fuel to the fire.
No one expected Neymar to move away from Barcelona last season which shows that in football anything can happen. Therefore, despite assurances, it should not be surprising if he does move in the summer.
