#2. Neymar

The former FC Barcelona star has been highly tipped to win the Ballon D Or in future and in order to achieve his dream he made a move to Parc De Princes. PSG bought him as their talisman who would lead them to Champions League glory.
The fact that PSG were able to sign Neymar not only represented that they are capable of spending big, but it also showed that they can spend big on the very best in the market.
No one expected PSG to pull off such a deal, but they did and now every European giant fears them in the transfer market and due to the Neymar effect, a club of Real Madrid's size has inserted Benzema's release clause at €1 billion, Isco and Asensio at €700m each, Carvajal at €350m, and Varane, Marcelo and Llorente all at €200m.
The impact PSG have made on transfer market since signing Neymar is the reason why he is No.2 on this list. Though many have called his move to Paris just a part of a bigger plan of his to move to the Bernabeu, in order to win the Ballon d'Or. But these are just rumors and nothing concrete can be established from it.
