9. Pepe (Real Madrid)
Pepe has developed into one of the world’s top centre-backs under the guidance of Jose Mourinho at Real Madrid. Now that the Portuguese coach has left the Bernabeu to return to Stamford Bridge, Pepe might be tempted to follow. Mourinho has been linked with a number of his former players at Real, and though Pepe might not be the best long-term option at the age of 30, his quality and experience would suit Chelsea well.
With Real Madrid being one of the clubs said to be considering a move for Luiz, a swap deal could take place involving these two players, and that would arguably suit both sides best, as Real would be landing themselves a more exciting and versatile player, while Chelsea would get the more solid and reliable option they desire.
Manchester City have also been linked with a move for Pepe this summer, as another former Real Madrid boss, Manuel Pellegrini, is keen to reunite with him at his new post at the Etihad Stadium. He is valued by the Spanish giants at around £20million.
