Answer
David Luiz was transferred from Chelsea to Paris Saint-Germain in 2014 for a fee of £50 million. This was a record fee for a defender at the time, and it helped to cement Luiz's reputation as one of the best defenders in the world. He has since gone on to win the Ligue 1 title with PSG, as well as the Coupe de France and the Coupe de la Ligue.
