Hi Semedo: Chelsea’s potential new-look 2017 defence including €40m-rated star

 CB – David Luiz

Another summer signing, David Luiz has been impenetrable this season.

Playing as a sweeper, slightly behind his other defensive partners, Luiz has been tasked with managing loose balls and being the last line of defence – and he has done the job magnificently.

Nobody thought he would be a very good signing, and he has proved everyone wrong.
