Marco Verratti
Despite recently admitting that he was not looking to leave Paris Saint-Germain this summer, Real Madrid would surely be an alluring prospect for Marco Verratti.
The Italy international is one of the finest young midfielders in world football, and could be a key figure in the heart of Real’s midfield for a decade.
With Sami Khedira set for the exit door and Asier Illarramendi facing a murky future, Benitez may need to bring in some reinforcements in central midfield.
Having already been hit by financial fair-play sanctions, PSG may well be receptive should Real make a massive offer for the player.
